(Start Confident, Slightly Exasperated)

"Alright, so I've reached that age where my hobbies are basically... avoidance. Seriously. My main pastime? Finding new ways to not do the things I absolutely have to do. I spent three hours yesterday researching 'ergonomic desk chairs'... because I was avoiding answering one email. One email! By the time I found the perfect lumbar support, I'd forgotten what the email was even about. Probably something vital, like, 'Your fridge is running.'"

(Shift to Grocery Store Frustration)

"And speaking of avoidance, let's talk grocery stores. Specifically, self-checkout. Who designed this psychological torture chamber? It's like they hired the ghost of a suspicious Soviet border guard to program the machines. 'Please place the item in the bagging area.' I DID! It's RIGHT THERE! 'Unexpected item in bagging area.' Unexpected?! Karen, it's a BANANA! You scanned it! You knew it was coming! What did you expect to be in the bagging area? A badger? A signed Picasso? CALM DOWN!

(Mime frantic scanning/glancing around) "And the pressure! You feel like the entire store is watching, judging your scanning technique. Beep. Too slow? Beep. Too fast? Did I double-scan that yogurt? Is security eyeing me? Suddenly, buying broccoli feels like smuggling state secrets. 'Just act natural... scan the kale... look innocent...' I swear, I leave there more stressed than if I'd just done my taxes... while being audited."

(Transition to Dating/Social Media)

"This constant low-grade panic translates perfectly to modern dating, right? Dating apps! It's like applying for a job where the only qualification is looking vaguely acceptable in bad lighting while holding a fish. 'Swipe right if you love adventures!' Buddy, your 'adventure' is trying a new flavor of Pringles. Mine is remembering to put the bins out. Let's be real.

(Mimic scrolling, looking unimpressed) "And the profiles! Everyone's 'not looking for drama.' Translation: 'I am the drama.' Everyone 'loves to laugh.' Yeah, at other people's misfortune, probably! And the pictures! It's all hiking shots. 'Look at me conquering this mild incline!' Sir, I can see the parking lot right there. That's not hiking, that's... walking slightly upwards near your car. Impressive."

(Shift to Roommate/Housemate Dynamics)

"Even home isn't safe! Living with people? Forget it. My roommate and I communicate entirely through passive-aggressive Post-it notes and strategically rearranged fridge items. I moved his expired milk to the very back yesterday. That's our version of declaring war. He retaliated by leaving ONE dirty fork in the sink. Just one! Sitting there... mocking me. It's like Cold War espionage, but with Tupperware.

(Lean in conspiratorially) "And the noises! Why is chewing so LOUD? How does one person generate the sound of a small avalanche just... eating cereal? At 3 AM? It's unnatural! I lie in bed thinking, 'Is that... granola? Or is he secretly dismantling a wardrobe in there?'"

(Bring it Home - Callback)

"It's all just... too much! We're constantly being scanned, judged, swiped on, passively-aggressived at... * (Deep breath)* Honestly? Sometimes I miss just... buying bananas from an actual human. Someone who doesn't accuse the banana of being 'unexpected.' Someone who might even say, 'Paper or plastic?' Remember that? Simpler times!

(Final Punchline) "But nah, I'll stick to self-checkout. Because interacting with a real cashier? That sounds terrifying. What if they... make eye contact? Or worse... make small talk? Nope. I'll take my chances with the paranoid robot overlord, thank you. At least it understands my deep desire to just grab my groceries and get the hell out of there... without being scanned."

(Smile, Nod, Exit) "Thanks, you've been great!"
