"What am I going to do?" Dan asked himself as he watched his tail wag back and forth in the mirror. There was a growing desire in his mind to chase his tail, to run from the dressing room, to do something other than sit here and stare at the mirror.
Dan's mind began to wander to different things he could do. It was getting harder and harder to even think about his situation as wrong. He felt his body start to move; at first it was a fidget, but then he felt his tail lash quickly back and forth. Unable to control himself any longer, Dan moved to a squatting position and began to lick his forearm, cleaning himself.
At least it's better than tackling a zebra, Dan thought as he continued to groom himself.
There was another knock at the door, "Dan, come out of there right now or I'm coming in." Dan's mom sounded very worried.
I have to do something soon, Dan thought, even as the desire to run out and jump into his mother's arms crept back into his head.
