I had a 7 year old girl brought to the hospital I worked out of at the time, while I was employed as a crisis intervention worker.
Flipping out, screaming, punching, kicking, biting, as they try to secure her on the stretcher. She kicks her mother in the face in the process, bad bloody nose, possibly broken, blood starts pouring out, 7 year old starts giggling and pointing at her mother as this happens.
