You can hug me (without the asking out loud part) (if you want to do that). I guess I'm in the 99% boat about hugs, at least. For the 1 time where you (hypothetically) come up to hug me and I failed to make the reciprocal interest-in-hug gestures and I didn't want it _AND_ I was unable to indicate that by words, facial expression, or body language (turn away, shake head) or I did indicate it but you hugged me anyway. there are the 99 times where i wanted a hug but was too shy/out of cope/feeling awkward enough that I couldn't ask.

I like the approach that one of our mutual friends has, about offering hugs - it is the spread arms out and say "hug?". while NOT moving. Then the huggee can indicate they'd like to continue the hugging action by either moving in towards the offering person or saying "yes" or "sure" or opening their arms up too. I have always had enough cope to shake my head or say "no thanks" when I didn't want a hug from that person on that occasion, because I trust that person to not be upset at me or think I am mad at them or whatever.
