hugs seems to be a little overused in today's society i think. to often i've been hugged by somebody who's name i couldn't remember for the life of me. it throws me offguard, and makes me wonder what i did that made this person decide it was ok to hug me.
that being said.. after the second meeting, with at least a reasonably personal conversation, i'm perfectly fine to be hugged by a female.. for guys, you have to be close enough to be family.
i don't think i need hugs, don't get them often enough to be able to tell
guess i'm just not a huggable person :P
