I am so freaking mad!

I chipped my front tooth today sparring a friend of mine. I know, it was stupid of me to box without a mouth guard. To make matters worse, when I went home my mom made a big scene instead of helping me out. Now I'm going to have to pay for this crap. I am so freaking pissed.
So what was the thing that made you the angriest recently and why?

My isp for being inept at everything possibly imaginable to do with the interwebz.

I thought somebody had stolen some PSP games from my desk at work. Then I found out I'd forgotten them at home >_> what a shame.
