Me on Regular days

Theses faces explains how i am basically everyday. I am sometimes happy and sometimes cranky or  moody. I tend to constantly change my mood, because i have a short temper. And i respond to things quickly. My mood changes based on the people or anything around me. I am mainly happy when I'm with my friends , my mood tends to change when something, or someone says something to get me mad. But sometimes my mood just changes out of no where. Like i can be happy at one point and then in one second I'm upset and mad at the world. I guess it because there wont be nothing on my mind at one point, then all of a suddenly I would begin to think about several things.
