I don't like being touched by most people, even friends and family. The most awkward is hugging, because people who are close to you - or rather, think they're close to you - expect it. I hate hugging in most cases, and if I'm in a situation where I'm expected to hug 1) I NEVER initiate it - it has to be the other person and 2) I try to make it the shortest hug ever.
I don't like having my face touched either, but fortunately this doesn't happen very often. The only real issue I have had with this recently was a very casual friend, someone I only knew through another friend, who was overly affectionate wih other women all the time. She would insist on hugging and kissing me, as she did with other people, and was totally oblivious to how uncomfortable it made me. I could live with the hugging - I've learned to tolerate that without showing how completely weirded out I am - but the kissing, no. She would try to kiss people on the lips even! Ugh!! I would hve to move very quickly so she would end up kissing my check instead. I would avoid this person as much as possible because of this, and I came to be so anxious about her trtying to huug/kiss that just the sound of her voice coming frrom a distance or from another room would make me jump.
In epitaph, the friend through whom I know this person recently "burned" me (the same one I posted about in The Haven), so I don't have to see the serial hugger/kisser anymore. LOL. And honestly, I feel very relieved by that.
