A friend reminded me about a kid I met when I worked in corrections. I didn't ask about their crimes too much, because it wasn't relevant; occasionally though I'd see the same kid week after week and eventually I'd say something like "what is going on with you?" Or "what this time?" That sort of thing.
This kid gave my favorite answer EVER, after some deep thought: "Well, I was chillin'. And then, I wasn't."
I feel like this response has a potentially broad range of uses.
