Oh, ain't you the Alpha male?

I thought I'd take this oppertunity to have a rant about certain people who's Ego need feeding daily in the form of staring at you. It happened to me today quite a few times, and annoyed me quite alot. I mean what do they want? My number, or a fight? (Because let's face it, that's the only real reasons you'd take such notice of a random person on the streets)

Anyway- it made me wonder what you can do to actually win one, I've had enough of being the mature person and looking away because to be quite honest, when a teenager stares you out, it does leave you feeling like the smaller person. So theres the question fourm, what do you do to win these phycological battles?
