Funny faces

part of my job is being able to keep a straight face at times when normally you would crack up or yell out something inappropriate..for example today ihad our TOUGHESt kid in his Time Out room, and I looked in and he was peeing all over the floor, I ignored it and continued w/ the time out procedure and went on w/ my day like nothing out of the ordinarly happened,
.
But every once ina while somethign happens where I cannot keep a straight face. the other day this kid was making the FUNNIES faces, honestly I don't even think he knew that he was making them, but they cracked me up so hard I had to leave the room totally unprofessional...sometimes I just have to laugh at my job, otherwise I would cry...a lot!
