I don’t wanna go…

Seeing her son is still in bed, Mary goes to wake him up for school. When she wakes him up he says, “But I don’t want to go to school mom.”
Mary quite annoyed at this childlike behaviour says, “Well why not? You have to go.”
The son replies, “But I don’t like it. The kids are mean to me, the teachers hate me, and everyone makes fun of me.”
Mary calmly replies, “I’m sorry son. But you MUST go to school!.”
The son says, “But whyyyy?”
Mary annoyed at the delay says, “Because you’re the damn principal!”
