You look like you just tasted something bad.

A 13ish year old girl stands in the bathroom brushing her teeth. She goes from side to side and in circles and brushes on the sides and in front. She spits and makes a face as she is about to put her tooth brush back on its rack. She happens to catch her face in the mirror, and stops. She tries to make it again but it isn't exactly the same. She drops her tooth brush in the rack and again makes the face perfecting it this time. She then leans on the sink thinking. She then straitens herself and makes another face. She continues with different faces adding in gestures and motions. She is enjoying herself. She adds objects from the bathroom to her poses and actions, all the while looking in the mirror and scrutinizing these faces and either approves of them or disapproves. When the latter happens the works on improving them until she has a different idea. Eventually she places all her bathroom props back in their places and calmly walks out the door turning off the light as she goes.
