Ok, there are times, where I get angry when something goes wrong at the computer, but I always keep myself within borders; I simply undo my mistake and/or (re)try it again. I may say some bad words, I admit it, but I'm never going too far, resulting in me at buying a new computer or one of it's main hardware pieces (such as keybord or the mouse). This German kid apparently does not have the amount of patience I have...
