I am contemplating tossing some paper at the teacher.
What would make you throw paper at the teacher?
Well she is a substitute. She is an easy target since she still doesn't' know her way around.
Teachers deserve respect and you throwing things at her is not correct even if they are a substitute. Treat your teacher with the dignity that she should have.
Are you judging me?
It is a tough job being a substitute teacher. You should try to make their job easier by paying attention and being nice instead of throwing paper at them. They are humans just like you are and have feelings.
