Years ago, I taught high school in a small suburban community in Florida. After my then-boyfriend substituted in my classes one day, my classroom was vandalized with threatening, offensive messages on the whiteboard, my desk, and the overhead projector and its screen. The contents of my desk were strewn across the room, and some personal property I had brought to my workspace was defaced. Overall, very little physical damage was done, but the event seriously shook my nerves.
