I am so sorry you had that happen to you. I am very anal about my desk and I would have almost passed out if anyone had “cleaned” MY desk. My kids laugh because even they know that one of my rules is you don’t touch my desk (they will even remind other students). They have learned to ask to borrow anything on my desk. If they would like to use the stapler (it gets passed around when an assignment is due) then they ask. I would consider this a personal violation and it would really bother me. Some people can be so inconsiderate.
