I'm sorry about that.
Hey, if he was being like that, you should tell the principal, or your homeroom teacher.
Once, we had a teacher that was SO BITCHY.
Called us disgraces, said she felt bad for our teachers and our parents, made my friends cry-
The "made my friends cry" was the final f**king straw.
Told the principal EVERYTHING (she did a lot more horrible stuff I haven't mentioned )
The teacher almost got fired.
If she yelled at us ONE MORE TIME, or said ANYTHING that upset us, she would get fired.
In summary, TELL SOMEONE.
