Hmmm...Artistic ability?

When I went to the school to pick Michael (6 yo ds) up today, the principal brought him to me.  He had written on the bathroom floor with a crayon.  He claimed the scribbles, but not the smiley face. lol.  The kid is in sooo much trouble.  Right now he is writing apology letters to his teacher and principal.  His principal is keeping him in from recess tomorrow to clean the floor.  I think he needs practice.  Maybe I will have him practice on my floors tonight.
