When i'm frustrated or mad, i do a lot of things.
1. Play (agressive) fighting games. (mostly mortal kombat)
2. Listen to hard music. (mostly rock, trance or techno with a hard bass)
3. Break something. (things that are not important)
4. Punch the wall. (one time i brused it and one time it went a little bloody)
5. Smoke a tabbaco. (i really need to quit)
