I need to work through this step-by-step.
Given information:
Since Sally is one of the sisters that each brother has, and each brother has 2 sisters total, that means th ere must be exactly 2 sisters in the family.
The 2 sisters are:
Therefore, Sally has 1 sister.
I need to work through this step-by-step.
Given information:
Let me think about this carefully:
Since Sally is a girl, she is one of the sisters that each brother has.
If each brother has 2 sisters, and Sally is one of those sisters, then there must be 1 additional sister besides Sally.
Therefore, Sally has 1 sister.
To verify:
Sally has 1 sister.

"Modern Life is Weird"
[Walk on stage]
You know what's crazy about being an adult? Nobody tells you that half of it is just googling things you're too embarrassed to ask real people. Last week I googled "is it normal for my knee to sound like bubble wrap? " The answer was either "yes, totally fine" or "you have six weeks to live." Thanks, internet!
[Pause]
I went to the doctor about it. You know you're getting old when your doctor looks like they should be asking YOU for ID to buy alcohol. This kid walks in with a stethoscope, and I'm like, "Did you just graduate... fr om middle school?"
But here's what really gets me – why do we act completely insane at the doctor's office? They ask, "How much do you drink?" and suddenly I'm doing calculus in my head. "Well, let's see, carry the one... I have a glas s of wine with dinner." Yeah, a glass. It's just a really big glass. It's a vase, actually. I drink wine fro m a vase.
[Mime drinking from large container]
And don't get me started on grocery shopping. Why do I need a PhD to buy shampoo? There's moisturizing, volu mizing, clarifying, fortifying... I just want my hair to be clean! I don't need it to solve my emotional pro blems!
Plus, self-checkout is a trap. They put you in charge of scanning your own groceries like you work there. Th en the machine starts screaming "UNEXPECTED ITEM IN BAGGING AREA!" Yeah, it's unexpected because I don't wor k here! I'm doing my best, robot!
[Pause for effect]
The worst part is when you're buying embarrassing things. Last week I had toilet paper, ice cream, and cat f ood. The machine froze, and the teenage employee had to come over. He looked at my items and I could see him thinking, "This person's having a rough week."
[Shrug]
Speaking of technology, my phone knows too much about me. It autocorrects "running late" before I even type it because that's apparently my catchphrase now. My maps app just assumes I'm lost. It doesn't even wait for me to ask for directions anymore. I'll be sitting on my couch and it's like, "Turn right to get to your kit chen."
And what's with password requirements these days? "Must contain uppercase, lowercase, numbers, symbols, the blood of your firstborn, and a haiku about your childhood fears." Then they're like, "Don't write it down!" Where am I supposed to store this information? I can't remember why I walked into a room!
[Pace across stage]
You know what else nobody prepared me for? How excited I'd get about cancelled plans. Someone texts "Hey, ca n we raincheck?" and I'm already in my pajamas like "Oh no! What a shame! I was so looking forward to puttin g on real pants!"
Because going out now requires preparation. I need three business days' notice. I need to charge my social b attery. I need to practice conversation topics. Remember when we could just... show up places?
[Final beat]
The truth is, we're all just walking around pretending we know what we're doing. But at least we're all conf used together. And hey, if you ever see someone at the store at 10 PM buying wine in a box and googling "why does my back hurt when I breathe?" – just give them a nod. We're all in this together.
[Pause]
Thank you, you've been a wonderful audience! Don't forget to validate your parking – unlike my life choices!

"Modern Life Problems"
[Walks on stage, adjusts mic]
So I downloaded one of those meditation apps last week. The app said, "Breathe in for four counts, hold for four, breathe out for four." I'm like, "Finally! Someone who speaks my language – a robot!"
[Pause]
But then it asked me to "clear my mind of all thoughts." Are you KIDDING me? My mind is like a browser with 47 tabs open, and half of them are just articles titled "You Won't Believe What Happens Next" – and I've never clicked on a single one!
[Gesture]
Speaking of technology – why do we call it "smart" technology when it's constantly asking me to prove I'm not a robot? I just want to buy shoes online, not pass a Turing test! "Click all the squares with traffic lights." I'm 90% sure that's just photos of my hometown.
[Shake head]
And don't get me started on voice assistants. I asked mine to play some music, and it started playing a podcast about ancient pottery techniques. That's not music! That's what my nightmares sound like! "Welcome to Clay Time with Karen..."
[Pause for effect]
Dating apps are wild too. Everyone's profile says they love "travel, food, and adventure." That's just a fancy way of saying "I eat meals in different locations." Congratulations, you're a tourist! I matched with someone whose bio said "professional napper." I was like, "Finally! A man who lists his hobbies honestly!" Turns out he was a construction worker. Different kind of professional napper.
[Shrug]
But you know what's really messed up? Grocery stores. They moved the milk to the back of the store! It's a conspiracy! They know we're busy people. I go in for three things – milk, bread, and eggs – and suddenly I'm wandering the aisles like a confused archaeologist, wondering how we survived as a species when we can't even organize a dairy section properly.
[Look around audience]
And can we talk about "contactless" delivery? The driver texts me: "Package is at your door." I live in a building with 200 units. It's like hiding a needle in a haystack, except the needle is a burrito, and I'm very motivated to find it!
[Pause]
You know what though? Despite all this madness, I remain optimistic. Why? Because I just figured out how to use my oven's timer function. Yesterday. I'm basically MacGyver now.
[Big smile]
Thank you, you've been a wonderful audience! Don't forget to tip your waitstaff – they're the only ones who still know what they're doing!
