Well it seems that it wasn't thrown out of the window, but against the wall. (That spot is now missing paint! LOL..)
We were in a fight, a big one. Discussion on all sorts of things, then she challenged me, I said whatever do it! Then she did it. So it's not entirely her fault, although she's the one who threw the thing. Now I got over it and I forgave her. We are peacefully together again now.
I'm saving for a new Nintendo DS Lite. Might get the black version as a reminder of what happened. (The wrekced one was white) I got all excited about it because I got homebrew running on it 2 days before it broke. Y'know, I'm a programmer.. =(
