I hate it when I'm writing or drawing, and put my pen down and it rolls off the desk, and then I pick it up and put it down, and it rolls off again.

I also hate when people make claims but can't back them up with evidence. I have a friend who says the theory of evolution is complete bollocks, and the only reason she can give for this is 'just because'.

Bad spelling is another thing I really hate.

Come to think of it, a lot of things really annoy me...
