what makes you easy to get angry? how can you handle it ?

There are many things that get me angry, however, it takes alot to push me over the edge where I will voice that I am angry. My biggest thing is unthankfullness. I cant stand it when either myself or someone else will go out of the way to do something nice and the other person just expects it or cannot even say a simple thank you, or gee that was really nice. I also get pretty upset when people talk badly of others again and again and again. I once read a saying that I just love. "To speak badly of others is a dishonest way of complimenting yourself." It can be used in alot of different cases.
