At lunch, you must act very nice. No trouble is allowed. If you cause trouble, there will be a consequence. At lunch, you get your lunch, pay for your lunch, and find your seat. You may talk to friends, or just eat in silence while you listen to them talk. Once you finish, you throw out your trash. When the bell rings, you go back to class.
In Ancient Greece they don't know science yet so they create a god to explain something that happen in a world like Why it lighting? They will answer because Zeus is angry some stuff like that
