what is the one quickest way to tick you off?

[ZTAngel]

Not giving me personal space. I think I talked about this in another thread but it is on my list of sure ways to piss me off. There's nothing that ticks me off more than when I'm standing in line somewhere (supermarket check out counter, fast food place, etc.) and the person behind me stands thisclose to me. I'll move up a bit and the person behind me will move in closer. I don't know why but it just gets me all anxious. My boss does it all the time to me. He'll come into my office and hover over my chair to look at my computer screen. He stands so close to me that his tie is smacking me in my face and his armpit is right over my head. Argh.
