You never know what mysterious things are lurking behind the teacher's desk. You may find tote bags filled with all kinds of weird props to help a teacher get through the day. I have a spinning wheel stashed behind my desk for those tough days when I need to fall back and regroup. I spin for a minute or two when the kids are not in the room and everything manages to fall into perspective. I even teach the students to spin.
The wheel of life goes round and round.
