Miss Nelson is too feminine to be assertive.
What it boils down to is, don't have respect for people who treat you kindly. The only two opinions the children can have for the teacher are disrespect, or fear. Really, the best relationship between an adult and a child is for them to have mutual respect and understanding of the other's position. It's obviously a lot harder for children to understand the position of the adult.

To get people to listen to you, you have to be nasty and threatening.
