When I went to England I noticed that people would apologize or even freak out if they as much as touched my little finger. At first I thought that maybe I was putting people off, but later it was explained to me that English people are just incredibly nervous about touching people they don't know very well.

I've been to conventions in quite a few countries by now, and England is the only country where most people asked for a handshake rather than a hug. :XD:

My own input: this is very true as a Brit there's a big taboo around touching anyone unless you're very close.
