I'm at Paris Baguette, a Korean lower-end coffee shop chain common in the Bay Area. The guy next to me has headphones on and his laptop on a stand. Or it's four middle-aged Latino women celebrating a birthday. Or it's a bunch of local high-school kids.

Do I lean over and say, "Hi, how are you guys doing? Really good coffee they have here, huh?"

I'm at the gym. It's a big-box gym. It's full of dudes wearing Airpods Max, a few couples in skintight athletic outfits, a few teens with phones on tripods filming themselves for Tiktok.

Do I come over, gesture for them to take off their headphones, and say, "Hi, how are you guys doing? That's really good form, on that lift, really good form. Keep it up!"

I'm waiting to cross a road. On the other side of the road is a Caltrain crossing. The traffic light cycle takes forever, and then the train comes and preempts it. And then preempts it again when people finish getting on. A crowd of parents with strollers are waiting to cross. People are returning from the farmer's market with bags of vegetables. People on bikes.

Do I lean over and say, "Hey, how are you guys all doing? It sure takes a while to cross. Wow!"
