I love hugs! They're just so quick and easy, and unlike kissing, school admins don't get all uptight about it. (I actually got one today, so there, it does make people feel good) plus, its kind of hard to be a bad hugger.
As for the whole guys-hugging thing, it's an epidemic at my school but you get used to it, especially if you do any sports, were group hugs are pretty much mandatory after scores or you win a race. Besides, it's better then having your ass smacked or your pecs grabbed by a male teammate or random dude.
