We had a kid running in the hall outside my classroom about an hour and a half ago, during one of the lunches. He slipped and bounced his head off the polished concrete floor. When I went to lunch, the EMTs were strapping him to a backboard, but the school nurse said he is OK. He was conscious and talking. We tell them repeatedly not to run in the halls, and to stay in their designated area, but it just goes in one ear and out the other. It still scared the heck out of us. We had a kid killed earlier in the year leaving school. Everybody was shook up over that, so this incident rattled everyone.
