Like Venus, I also hate the "you look okay, thus you are okay" attitude.

I get really annoyed with people who walk on the left side of the hall/sidewalk. We drive on the right side of the road (here in the US), so why the **** would we not walk on the right side of the sidewalk? So many awkward near collisions could be avoided.

I get very upset when my ADD causes me to make stupid errors. For example, I might act as if 5+2 =9 while solving a larger math problem, because I absent-mindedly add the 2 twice.

I have more; I'll add them when I remember them.

And SunAngel, that is a hilarious story!
