My gym teacher, and a teacher that knows me but doesn't have me. (Though.. he did say he wants me in his class(es) next year. I laughed and he said, "I'm serious o_o")
And its not that bad to have a parent/step-parent at school until they start trying to punish you for what you did, at school, at home. I am not talking about getting bad grades or anything. I'm talking about talking back to them in class or talking back to any teacher really. Things that normally wouldn't have the parents involved.
(Yup. Majority of the time, parents don't find out about their student(s) talking back to a teacher. Its handled in school)
You should shout from your room "God That Gym teacher is so annoying/gay/hawt (Take your pick)" While they are there then walk into the room and be leik "Oh....Hai..."
