(You are a vampire. You have a bf who's 2 years bigger than you and very tall. He's name is Aaron and he's a human. No one knows you are a vampire and you are the only vampire in this school. Whenever you feel thirsty you drink his blood.)

In school

You and Aaron are in the classroom, sitting in same bench, the bench is in the corner of the last bench. Not that people can see them. Now you are thirsty but you can't go or do anything cause teacher doesn't allow to go.
