and it was a boy touching a girl's butt. In Korea, PDA is highly frowned upon. I saw a young (straight) couple this afternoon standing at an intersection; the man was lightly grazing his girlfriend's butt with his fingertips behind her purse so that passersby wouldn't notice. I thought it was a really sweet (and kind of subversive!) way to connect in a place where you're not supposed to make much physical contact with the opposite sex in public.
