Funnily enough, it doesn't make me angry if I'm the one getting close to someone, even if I don't know them. That's easy to handle, probably because I'm controlling the situation - someone else forcing themselves into my space though is another thing entirely!

We were taught to "ask permission" before invading their space. Surely if you visit an iridologist, you know their going to get "up close".:willy_nilly:
