The university dormitory is a public place, not your home. College students like to transform their dormitories into their own homes and dress up beautifully. The wall is decorated with many posters and graffiti. After graduating from college, if you doodle on the wall, you need to paint it white and restore it to its original state. Freshmen coming to the dormitory will leave a good impression. If there is graffiti, it is vandalism.
We can't doodle in the school dormitory. Even if there is graffiti, the dormitory administrator will be angry when he sees it. Restore the reasons on the wall, or he will be punished by the school. So we must take good care of dormitory property.
