Fool Zero I think my reactions to people standing close to me is some what similar. However, I think when they first enter my personal space I do kind of feel a danger signal. However I am able to stop and ask myself similiar questions. Often I may do a subtle retreat to a safer distance until I figure out there intent. The other day golfing one of the guys I was playing with came and stood a little to close to me. This initally bothered me but after I assess it I was OK with his closeness. By the end of the round I got used to it and even kind of liked it. He wasn't coming on to me, it was just his way of interacting.
