What would you do if someone had a crush on you? How would you handle it?

Um.. is it bad if I say "Depends on who"? xD

Aaaaaanyway... for 99.9% of the population... first I'd be extremely confused as to the hell WHY, and then get incredibly shy and flattered, and then try to figure a way to be as kind about it as possible and keep it from going all awkward.

Have at it.
