The first is that they like singing in the dormitory. If this roommate sings well, forget it, but many of them sing badly. Moreover, they unconsciously feel that they are singing the sound of nature, and they have to shout a few times in the dormitory every day, otherwise they will feel uncomfortable all over. Some people sing really loudly and go to Causeway Bay out of tune. What this kind of people hate most is that even if someone is resting in the dormitory, they will sing a few times from time to time. This ugly singing sounds disgusting.

Second, you smoke in the dormitory. You know, the dormitory is not a place for you alone. Some people are so addicted to cigarettes that they smoke in the dormitory when they have nothing to do. The whole dormitory is like a fantasy movie. It's just looking at flowers in the fog. Secondhand smoke is extremely harmful. Many people have problems such as rhinitis. If you smell the smoke, it's unbearable to death, but you advise him to go out and smoke, but he is still unwilling and often at home. After all, smoking is your business, whether you like smoking or not is nobody's business, but if your roommate can't smell the smoke, you can honestly go to the toilet or the corridor to smoke. After all, it is not difficult to influence others because of yourself.

The third is to disturb others' sleep. This kind of roommate is really annoying. You know, the dormitory is just a place to sleep, but many times, roommates don't want you to have a good sleep at all. They will play games in the middle of high school and open their voices. I will scream loudly when I die, or I will talk to my partner on the phone after twelve o'clock. It's really annoying
