Trapped in School (girls only)

Well, you got detention (Hey, No one messes with your best friend!) and you have to stay there for the whole day. The door is locked from the inside, so no one can get out. Around 1:30, the detention teacher says "I have to go to the doctors, behave, the camera sees everything you do" and leaves. You decide to take a quick nap. But when you wake up, it's 4:30! Only one person is in there. He is sleeping too! What do you do?
