I describe myself as temperamental for the simple fact that it doesn't take much to agitate or anger me. To me temperamental means that someone is on edge at all time and is ready to snap at any minute. I honestly feel like that a good percentage of the time. Luckily it hasn't gotten me into too much or a significant amount of trouble.
