Kids Do The Strangest Things

The other day I went into Graces room and I noticed on her wall right next to where she sleeps were a ton of little marks. She had picked her nose and wiped her fingers on the wall - gross. I made her clean her wall and told her not to do that again. So this morning I went into her room and what did I find on her wall - a piece of tissue taped to her wall that she had clearly used. I don't know if I should be mad or proud at how clever she can be.
