I hate when I'm using Internet Explorere 7, and I right click, so that I can open a link in a new tab, but it opens in a new window, it pisses me off.
Also, I hate it when I miss a show I wanted to watch, because I am too dumb to remember to watch it.
I also hate it when the numbers are up on this site late.
I hate it when I'm on the computer or playing my PSP and someone is over your shoulder looking at you play the game.
Much more, but I can't remember
