I used to go to school in small groups, and no one was uncomfortable at that time. Maybe the dormitory can also be a group of two or three people. A person in charge is responsible for assigning tasks and reminding members to be on duty. Members can remind others when they think of being on duty. After all, they will be fined together. You can also set an alarm clock every day, which group of alarm clocks will be on duty. The head nurse will remind the team leader. It may be said that "our group is on duty today" is better than "your group is on duty today", so try to remind the members of the group as much as possible, and then there is no possibility of causing personal embarrassment. People have a sense of collectivity, which is easy to solve.
