This is one thing I really like about myself. I rarely get mad.
When something unfortunate happens, my mind automatically thinks of all the positive things that could come of the bad situation.
The only time I ever do get mad, or at the very least annoyed, is when someone who is obnoxious won't stop talking to me. I try to stay nice and ignore them without really ignoring them. I'll reply to one or two things, but seem bored with the conversation, or make it look like I got distracted by someone else.
It just really annoys me when people hang on me, or won't stop talking to me. Especially if I'm not in the mood to talk.
If I ever am mad, I'll text my best friend and sort of vent to her and get some feedback as well. If that doesn't work, then I just deal with it and move on.
