I get annoyed when my daughter decorates her arm with her social security number as if she is a recent refugee from the human rights tragedy that is the social security office.
On the other hand, I can appreciate the artistic creations that one of her classmates creates on her hand during class. My point? If you're going with the body art by Crayola, be sure that you don't go to school with any identity theives. Also, if someone in school is going to draw on your body, make sure it’s not the ‘tard in the helmet.
