Cayendo en Rabbit Holes

Roberto has a theory about the word "but." Whatever you say before it gets erased by whatever comes after. "You're beautiful, you're smart, you're kind, but…" — everyone braces for the shoe to drop, and the shoe always drops. In this week's rabbit hole, Rui and Roberto start with one small linguistic observation and wander through the entire toolkit of everyday persuasion — compliment sandwiches,...

Roberto hired a cleaning lady who is genuinely great. She cleans his apartment faster than he ever did and to a standard he could never quite reach on his own. The problem — if you can even call it a problem — is that she takes initiative. She threw out his almost-empty bottle of favorite hot sauce because there was a new one behind it. She reorganized his bathroom and closet, swapping items betwe...

Google's Notebook LM can generate AI podcasts on a research topic. The podcasts feature two AI voices talking to each other and, weirdly, breathing . Actually breathing, the way humans have to. It is deeply unsettling, because, obviously, AI doesn't need to breathe. Somebody added those sounds on purpose so the whole thing would feel more human, and instead it lands as the exact opposite. In this...

There's a Spanish saying: es de sabios cambiar de opinión — changing your mind is what wise people do. Roberto lives by it. He experiments constantly, gives things a fair trial, and if the data doesn't back up the plan, he quietly reverses course. His most recent experiment: after not using a cleaning lady for a year to try doing it himself, he quietly rehired a new one this morning after running...

Roberto had a custom belt buckle made for himself. Five stars on each side — one for every thousand lessons he taught over four and a half years on the platform where he first met Rui. He's showing it on the podcast this week, which is not something he'd normally do; he describes himself as a very private person, and this is a piece of his life almost nobody has seen. In this rabbit hole, Rui and...

The U.S. official who chose the targets for the atomic bomb had once visited Kyoto, years before the war, and fallen in love with a garden there. When it came time to make the decision, he pulled Kyoto off the list and put Nagasaki in its place. Because of one trip years earlier, millions of lives were rerouted forever. In this week's rabbit hole, Rui and Roberto pull apart the butterfly effect —...

Roberto has a phrase he loves: fear makes the tiger look bigger. If your reaction to a situation is emotional, your brain quietly inflates it until it doesn't match reality anymore — and half the time, nobody around you has any idea it's happening. In this week's rabbit hole (a direct continuation from Episode 29), Rui and Roberto start with the everyday moments where nobody has taught you how to...

Roberto has noticed a pattern. When someone starts making a positive change — hitting the gym, cleaning up their space, cutting back on drinking — other good things quietly start showing up in their life too. New opportunities. Better sleep. That indefinable "glow" where someone looks different and you can't quite say what changed. In this week's rabbit hole, Rui and Roberto try to figure out why...

Cabo Verde and Mexico both got knocked out of the World Cup — and both got welcomed home like champions. Meanwhile the United States, got blown out by Belgium, and nobody is throwing them a parade. In this week's rabbit hole, Rui and Roberto dig into why underdog stories hit so hard, and what the whole conversation reveals about the American habit of assuming we're the center of the sports univers...

Roberto has a black guitar he doesn't play. It sits in his condo as decoration, and if you ask him about it, he might tell you the real story: it reminds him of a girl with black hair he had a thing with 23 years ago, when he was 17. Rui has a painting of a Krispy Kreme burning down — a citywide inside joke in Atlanta that he's about to hang in his new Boston apartment, where nobody will have any...

Roberto comes out swinging in this one: he thinks Canelo Álvarez — the most famous Mexican boxer in the world — is a disgrace to Mexican boxing. Fixed fights. Hand-picked opponents. Hydration clauses. Even contracts allegedly forcing opponents to lose. In this week's rabbit hole, Rui and Roberto trace the messy line between professional sports as a sport and professional sports as a business — thr...

For two years, Roberto worked at the same coworking space, finished his coffee, set the empty cup in the sink, and walked out. Until two weeks ago, when he spotted a tiny sign he'd somehow never noticed before: please wash your cup when you're done. Now he's spiraling — has he been doing this wrong the whole time? Has everyone been quietly judging him? In this week's rabbit hole, Rui and Roberto t...

A barista hands Rui a coffee and tells him it tastes like a strawberry Pop-Tart. Rui is skeptical — there's no way this is going to taste like a strawberry Pop-Tart — but he tries it, and… she's not wrong. Why do experts get to use words that don't seem to belong, and how come they're usually right? In this week's rabbit hole, Rui and Roberto start with the strange world of unboxing videos and end...

Roberto goes to the mall by himself on a Sunday — eats sushi, watches a mediocre movie, sends a friend a random text on the way out. By the end of the night he's bar-hopping with two friends, eating tacos at midnight, and laughing harder than he has in weeks. None of it was planned. And Roberto, by his own admission, is a planner. In this week's rabbit hole, Rui and Roberto try to figure out why t...

Roberto's first email was named after a 1973 Mustang nobody his age recognized. Rui's was a crude reference to an obscure college football player nobody would recognize either. Both of them were dead convinced they had the coolest email address on the planet. In this week's rabbit hole, Rui and Roberto take a generational lap through pop culture — what used to be cool, what tech actually wins, and...

Rui blows a tire on his birthday in a sketchy part of town and somehow coasts to a stop in the parking lot of the only tire shop within miles — closed, but with a stranger standing outside who fixes it for ten dollars so he can still make his golf tee time. A miracle? A gift from the universe? Or just statistics doing what statistics do? In this week's rabbit hole, Rui and Roberto pull apart what...

Elisa speaks five languages — German, English, French, Spanish, and Dutch — and is studying Korean on the side. She's lived in Australia, New Zealand, the Netherlands, Mexico, and now Canada. And when Roberto first heard her speak Spanish, he didn't think she was German at all. So what's her secret? In this week's rabbit hole, Rui meets Elisa for the first time and the three of them dig into what...

Roberto walks into a sushi restaurant and the menu has so many pages he can't pick a roll. Rui opens Netflix and his food goes cold before he settles on a show. We've all been there — but at what point did having more options stop making life better and start making it worse? In this week's rabbit hole, Rui and Roberto pick apart the strange modern problem of being saturated with choice, from fast...

Every adult has a list of things they really don't want to do — and somehow has to find a way to do them anyway. Editing a paper. Going to the gym on a day you'd rather sleep in. Spending time with your partner's social circle when it's not your scene. So what actually works? Rui and Roberto trade strategies in this week's rabbit hole and end up somewhere unexpected: the answer might be less about...

Roberto just turned 40 — and he still doesn't feel like a real adult. That kicks off a conversation about "las pequeñas cosas": the tiny, almost stupidly simple things that quietly make life better. A woman jamming to music behind the counter at the Oxxo. A perfectly clean apartment on the morning of your birthday. A black coffee that turns a workday you didn't want to do into something tolerable....

Rui's friend Ana joins the podcast — and she's not just any guest. Her wedding in Colombia is the reason Rui started learning Spanish in the first place. Ana grew up between Brazil, Colombia, and the US speaking three languages, and in this conversation they explore whether your personality actually changes depending on which language you're speaking, the vocabulary gaps every language learner hit...

Why are humans wired to love stories? Rui and Roberto explore this from evolutionary psychology to personal taste — starting with how oral storytelling was the original way knowledge passed between generations (and how the game of telephone probably warped history along the way). Roberto shares his frustration with school history classes that prioritized dates over narrative, and they discover the...

What are the minimum requirements to actually be an adult? Rui — in the middle of his PhD and job searching at the same time — and Roberto build their list: cooking, doing your own laundry, dancing (yes, dancing). They debate whether keeping a plant alive counts, whether pets are proof of maturity, and how your 20s are about proving you can do things while your 30s are about just being functional....

We've all had that moment — someone confidently explains how something works, and you have to say: "that's not how it works." Rui tells the story of a friend who asked him to build an electric drone without understanding the battery limitations. Roberto shares his evolution from being a "correction enthusiast" as a kid to his current rule: only correct people when they're paying you. They also dis...

Shruti joins the podcast for a conversation that covers her recent trip to Mexico City — from Indian-Mexican fusion food at Masala y Maíz to learning salsa dancing. She also talks about a unique challenge in her professional life: using translators for difficult medical conversations in Spanish. Plus, Rui shares his own experience in Cancún and they discuss what makes Mexico City such a magnet for...
