That's really interesting about the Mensans. I used to aspire to be part of Mensa when I was a child.. hilarious to me now as those people are like geniuses.I am from a non-hugger upbringing. I was introduced to "huggers" by my wife, who is a member of Mensa. Many Mensans grow up feeling separated from their peers because of their intelligence or have suffered taunts because of their geekiness, so when they meet each other they want to show mutual acceptance by hugging. I am not a member, but when I attend an event, I do end up hugging many of the people when we are introduced. There is a protocal that if the person you meet has a nametag with a red colored sticker, they happen to be a Mensan that either does not hug or would like to be asked first. I have found after ten years of exposure to that environment, I am much more apt to hug members of my family when we meet than I was before. I can appreciate the platonic side of a hug now, rather than thinking of it as always being romantic.
