I noticed a small white board on a wall the other day. It had a message written on it and I had a flashback! When I was in university, we had white boards on our doors in the dorm. If someone dropped by to see us and we were out, a note would be left on it. If someone took a message on the phone in the hallway, a name and number would be written on it. I haven't been in a dorm in many years, but I have a feeling students do not need white boards anymore!
