I'm interested in this because for some reason I am able to stop 'huggers' and keep them at a distance. I dislike being hugged by people I don't know intensly, and somehow this is communicated to them. Maybe I flinch slightly as they approach, maybe I stiffen up, I'm not really sure, but a friend was complaining about a mutual aquaintance who routinely hugs on meeting anyone and I realised she doesn't do it to me. She did the first time we met but she soon stopped. I don't really know what I do, I wish I could explain it. I do think if you feel strongly about things your body language passes that on.
