Son's experience in the bathroom

Our son was in the bathroom taking a bath. He was in there for a little and he heard a scraping noise coming from the wall behind the toilet. On the wall behind the toilet there is a Psalms 23 picture and a small mirror. When he looked in that direction, the mirror was thrown off the wall and into the mop bucket sitting beside the toilet. He hurried up, got out the tub and dried off and came down running to tell us what happened.
