I can deal with the big things, I'm one of the most mellow people ever, but the small things really get to me.
example. changing the time on my alarm clock. I have to change it a lot. when I have to change it from a half hour to a full hour, clicking the flipping button 30 times, or holding it in for 84 seconds to get it set up to the hour or half hour really ticks me off. I need a NEW CLOCK!
.. so what little things annoy everyone else.
