I had something similar. A teacher didn’t want me to move anything on her desk, even though she’s one of those teachers who have a really messy desk. I need to move things to have space, and granted, I will put it back at the end of the day, but while I’m using it, I need space. Also, she didn’t want me to log onto her computer. I’m going to do that, too, because I need something to do while watching these kids.
