I have three stages of anger
1) Stubborn, I will keep trying to MAKE it work then end up screwing it up more.
2) Pissed, at the piece (eg. "you stupid piece or crap", "F*ckin piece of s**t", language gets worse the longer I keep trying). It is the materials fault or the machines or whatever I am working with, it is NOT the human!
3)Final stage, Cry.
I will add a 4th stage now... Condolence or self pity: take pics and post on HAF for everyone to enjoy or compare.
