What are the selfish behaviors in university dormitories?

In the dormitory, several people live in a public environment, and everyone's work and rest habits are definitely different, but there are such people who only care about themselves and don't care about other people's feelings. When they sleep at night, they should listen to music, wear headphones and play foreign sounds to disturb others' rest. Some people are taking a nap when they are tired, while others ignore it, talk to their partners on the phone, watch movies and play games, and keep nagging. Disturb others to rest or study. In public environment, we must consider the feelings of others. Don't disturb others because of your behavior. If you are embarrassed, it will destroy the feelings between friends.
