One time i was in the elevator at my apartment building - i live in a college town - and these two student age guys were talking, and theyre like, "oh what a horrible thing i had to do today - i dont know how anybody does that for a living etc etc" and the city had just opened a new recycling center so im thinking maybe that? But i take a chance and i say, "you guys are talking about computer programming, arent you?" And theyre like yes! How did you know? Im like, hey i used to be young and beautiful... it was totally funny, in a way!
