This is a growing problem within our schools these days. If you're not familiar with it (or you might be one, and don't even know it) you should read up on the subject. It was getting bad back when I was teaching. I can only imagine what it must be like for teachers now.
Sociologist, psycologist, surrogate-parent, baby-sitter, teacher. Give 'em a break. They've got a LOT on their plates.
