Ha in high school yea. now I've talked to enough of them to know they're thinking about something completely random and unrelated to me and often nothing at all, which I find the most interesting.

Like they might have literally just been staring at a tree for five minutes. And then I talk to them and they're like 'I was just looking at this tree."

Especially these days, people seem increasingly surprised that a human is actually talking to them in real life.
