I need to work through this step-by-step.
Given information:
- Sally is a girl
- Sally has 3 brothers
- Each brother has 2 sisters
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:
- Sally
- One other sister
Therefore, Sally has 1 sister.

You ever notice how adulthood is just a series of tiny defeats you pretend are victories? Like, I finally got around to cleaning my apartment this weekend. Took me three hours. I stood there staring at the pile of laundry on my bed, thinking, "This is it. This is my Everest." I separated it into whites, colors, and "these are basically rags now." Victory number one.
Then I tackle the kitchen. There's this one dish from, like, two weeks ago. It's not even food anymore—it's a science experiment. I scrape it into the trash, and it fights back. Splats everywhere. Now I've got a new stain to deal with. But hey, progress! I load the dishwasher like I'm performing surgery. Make sure everything's facing the right way, because if that fork's upside down, the whole cycle's ruined. Rinse, repeat. By the end, my kitchen sparkles. I step back, hands on hips, feeling like a goddamn warrior queen. Then I realize I forgot to actually turn the thing on. Another hour wasted. Adulthood: zero. Me: still delusional.
But the real killer is trying to adult with technology. I signed up for this meal prep service because I'm "getting my life together." They send you recipes and ingredients in a box. Sounds perfect, right? First box arrives: salmon, quinoa, kale. I'm hyped. I follow the instructions to the letter. Chop this, sauté that. Set the timer on my phone. Twenty minutes later, dinner's ready. It looks exactly like the picture... if the picture was taken during a mudslide. The salmon's rubbery, the quinoa’s like gravel in a salad, and the kale? Tastes like I’m eating a lawnmower’s feelings.
I eat half of it anyway because I spent thirty bucks, and now I'm committed. Next morning, I’m bloated, gassy, staring at my reflection like, "This is what discipline looks like?" Nah, this is punishment. I cancel the subscription faster than you can say "regret." Back to DoorDash, baby. At least with that, my tiny defeats come with free delivery.
And don’t get me started on dating. I went on this date last week. Guy seemed normal online—engineer, loves dogs, cooks. We meet up, and he’s grilling me like it’s an interrogation. "What’s your five-year plan?" Bro, my five-minute plan is shaky. I say something vague about career growth. He nods, then launches into his. Owns a house, stocks portfolio, weekend hikes. Meanwhile, I’m thinking, "Cool, I own a succulent that’s somehow still alive."
By dessert, he’s talking crypto investments. I tune out, nodding like a bobblehead. Bill comes—he pays, thank God. Walks me to my car, goes in for the hug. I dodge like it’s a jump scare. Text him later: "Had fun!" Lie. He replies: "Let’s do it again soon." Panic. Block. Swipe right on the next profile: "Just here for the vibes." That’s me now. Vibes-only adulting. No plans, no quinoa, just surviving one tiny defeat at a time.
Thanks, you’ve been great!

"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!
