Написать на британском языке правила совместного проживания в одной комнате

If you live in one room with your roommate, you should follow simple rules if you dont want troubles with your new friend. First of all, you must not be loud in the room. You can turn on music only if your roommate doesnt mind. 

Then you should keep your room clean. And the main rule is not to touch his things without his permission. If you follow these rules, life in one room will be happy and interesting.
