I need to think through this step-by-step.
Given information:
Let me work out how many sisters are in the family total.
If each of Sally's 3 brothers has 2 sisters, and all the brothers are in the same family, then there must be 2 sisters total in the family.
Since Sally is one of those sisters, and there are 2 sisters total, Sally must have 1 sister.
Therefore, Sally has 1 sister.
1
Reason: If each of the 3 brothers has 2 sisters, there are exactly 2 girls in the family. One is Sally, so she has 1 sister.
Tests an AI's understanding of number representation
No, 9.11 is not greater than 9.9.
To compare these decimal numbers:
Since both numbers have the same whole number part (9), we compare the decimal parts:
Therefore, 9.9 is greater than 9.11.
No. 9.11 is less than 9.9. Think of 9.9 as 9.90; comparing 9.11 to 9.90 shows 11 hundredths < 90 hundredths.

So I'm 30 now, which means I'm officially an adult. Apparently. Though I still feel like I'm just a confused teenager wearing a slightly more expensive t-shirt.
You know what nobody tells you about being an adult? How much time you spend pretending to understand what other adults are talking about. I was at a dinner party last week – because that's what we do now, we have "dinner parties" instead of just "eating pizza on the couch" – and someone started talking about mortgage rates.
I just nodded along like, "Oh yes, rates. Very mortgage-y." Meanwhile, I'm thinking a mortgage is something you get at a fancy French restaurant.
mimics sophisticated nodding
"Mmm, yes, I'll have the mortgage, medium rare."
And don't get me started on small talk with neighbors. I live in an apartment building, and there's this unspoken rule that you have to acknowledge each other in the hallway. But what do you say?
"Hey, nice... existing near me."
"Thanks, you too. Love what you've done with your... door."
The worst is when you're both waiting for the elevator in complete silence. It's like a hostage situation, but with more awkward eye contact. You're both just standing there, praying the elevator comes before one of you has to comment on the weather.
stares ahead uncomfortably
"So... it's very... outside today."
I tried being one of those people who meal preps. You know these people? They spend their entire Sunday cooking seventeen identical containers of sad-looking chicken and broccoli. I bought all the containers, felt very organized, very adult-like.
Week one: Perfect little meals, properly labeled. I felt like a productivity guru.
Week two: I'm eating cereal for dinner and using the containers to store my collection of takeout sauce packets.
holds up imaginary container
"Ah yes, vintage soy sauce, 2023. A good week for Chinese delivery."
Speaking of food, grocery shopping as an adult is weird. When you're a kid, the grocery store is magical. Everything looks amazing. You want the cookies, the candy, the sugar cereal with the cartoon mascot.
Now I walk through the store like a tired parent, even though I don't have kids. I'm just disappointed in all my options.
walks slowly, shaking head
"This yogurt has too much sugar. These crackers have no fiber. Why is everything either terrible for you or tastes like cardboard had a baby with sadness?"
And I've started doing this thing where I read nutrition labels like I understand them. I don't. I just nod thoughtfully and put things back like I'm some kind of wellness expert.
"Hmm, seventeen grams of... things. That seems like too many things."
The real kicker is when you find yourself getting excited about household appliances. Last month, I spent twenty minutes explaining to my friend why I love my new vacuum cleaner. TWENTY MINUTES. About a vacuum.
"It has three different settings! And look at this attachment! This little brush thing goes in corners!"
My friend just stared at me like I'd been replaced by a suburban mom from 1987.
But you know what? I've decided to embrace it. Yes, I get excited about good storage solutions. Yes, I have opinions about thread count. Yes, I've used the phrase "back in my day" unironically, and I'm only thirty.
shrugs confidently
Because being an adult isn't about having it all figured out. It's about confidently pretending you know what you're doing while secretly googling "how to fold a fitted sheet" for the hundredth time.
And if that's not the American dream, I don't know what is.
pause
Also, if anyone actually knows how to fold a fitted sheet, please find me after the show. I'll pay you.
mic drop gesture
Thank you, you've been a wonderful audience! Don't forget to tip your servers and call your parents – they're worried about you!

I tried to get my life together, so I bought a smartwatch. Nothing says “I’m taking control” like strapping a tiny judgmental coach to your wrist. It buzzes every hour like, “Time to stand!” I’m like, “I’m on a bus.” It’s like, “Stand emotionally.”
It tracks everything. Sleep, stress, calories, my self-esteem. The other day it congratulated me for a “workout.” I was like, “What did I do?” It said: “You aggressively looked for your keys.” Great. Next week I’ll get a badge for “overthinking at 3 a.m.”
Notifications are out of control. My phone dings like I’m on call for a hospital, but it’s just my group chat: twenty adults sending thumbs-up reactions to a photo of soup. The group chat has subplots. One person’s mad, one person’s on vacation, someone’s dog has opinions. I miss when messages were simple. Now a single “K” can end a friendship.
Streaming services are the same. I have subscriptions to five platforms and somehow there’s still nothing to watch. They keep asking, “Are you still watching?” That’s rude. Don’t check in on me like that. If you care, ask how I’m sleeping. Ask if I’ve seen the sun. Don’t be like, “Hey, pal, still in those same sweatpants?” Yes. We’re a team.
Passwords have gotten ridiculous. Every site wants “eight characters, a capital letter, a number, a symbol, your childhood nickname, and the last four digits of a secret you’ve never told anyone.” Then it’s like, “This password is too weak.” Too weak? It’s stronger than me. I’m using that password to log into my feelings.
And two-factor authentication is a haunted house. I’m sitting at my laptop, it says it texted a code. My phone says it emailed the code. My email says it sent a push notification. My push notification says, “We noticed a suspicious login.” Yeah, it’s me! I look like this.
My mom texts like she’s defusing a bomb. She’ll send one sentence spread across twelve messages. “Hi.” “It’s me.” “Mom.” “Are you busy?” “Don’t worry.” “Everything’s fine.” “Call me.” That is not fine energy. Then she FaceTimes, camera under her chin, ceiling fan spinning like I’m being interrogated.
I tried meditating because everyone says it helps. I downloaded an app that yells at me to relax. Nothing like a British guy at 7 a.m. saying, “Let the thoughts pass like clouds,” while my mind is a tornado hitting a trampoline park. The app sent me a streak reminder. “You missed yesterday.” Oh cool, I’m failing at sitting still.
Self-checkout has turned us into unpaid employees. The machine is like, “Unexpected item in the bagging area.” Yeah, it’s my dignity. I love when it needs approval. I’m standing there holding broccoli like I got carded for vegetables. A teenager with a magic key wanders over like, “You trying to steal lettuce?” No, but ask me again and I might.
Dating apps feel like job interviews where no one has benefits. Every profile is a list of demands. “Be adventurous, love dogs, climb mountains.” Can we meet at a coffee shop and just be honest? “My hobbies are sitting and not climbing.” And stop asking for “someone who doesn’t take themselves too seriously.” You’re holding a fish in 80% of these photos. You are very serious about the fish.
Working from home gave us a new language. “You’re on mute.” “Can you see my screen?” “I think there’s a lag.” That’s not the internet—that’s my personality. I love when someone says, “Let’s take this offline,” and then schedules three more meetings to repeat the meeting we just had. My smartwatch is in the corner like, “Heart rate elevated.” Yeah, because I heard “circle back.”
Anyway, my watch says it’s time to stand. I’m going to consider that a full-body workout and reward myself with soup. I’ll send a photo to the group chat and we will never be free.
