1. The way you treat me. If you treat me like shit... I will not hesitate to do it back.
2. One word. Stupidity. If you are a fucking retard, and I am trying to talk to you... if you hear me yelling: Shut up.
I usually stay calm, but I get really angry when someone talks to me in a disrespectful manner. Also, I hate scammers a lot because they are dishonest and thoughtless. It's tough to handle when people take advantage of others just to benefit themselves..
