There is an office in your school where no one conducts a lesson, you can say that it is just a warehouse for things. The door is usually always closed, but walking down the hallway today, the door was open. You decided to go into the classroom to see what was there. It wasn't that bright, one light bulb was on and a guy was sitting under it, who was painting some kind of picture. "Oh, did I not close the door?.." He said when he noticed you.
