It takes a lot to get me angry. You can pester me for hours without me getting even annoyed if I'm in the right mood.
The only time you'll get me angry is when I try to get away to have some alone time and recharge, and you try to stop me. When I don't get my alone time, I will rip you apart relentlessly. However, if you're one of my brothers, you automatically make me mad. It's not like we don't get along, but it's the typical sibling love/hate relationship.
I remember at Christmas, my house was filled with relatives for four straight days. The only alone time I got was when I went to the bathroom, and even then people were knocking on the door. I had enough and went to go lock myself in my room when no one was in there. My aunt tried to stop me and wanted me to play a board game with the rest of the family. After she kept pestering me that I need to be more social like the rest of them, I screamed at her and slammed the door in her face. Yeah, I got my alone time after that!
