What behaviors of college roommates make you think Ta is selfish and utilitarian?

Mean and love to take advantage. It is really speechless to meet such a roommate. It is almost impossible for you to ask him to pay. He will remember how many things you used and will chase you back.

In the dormitory, if you want to sleep, they will turn on the TV and talk as if you are not at home. When you wake up, they will say, I only sleep all day. Do I need your permission to sleep?

They don't even dare to turn on the lights when they sleep, but when you walk underground, you will scream at the top of your lungs as if you had killed someone.

Never throw garbage into the trash can, and never mop the floor when on duty. These five people are really good. Moreover, in a small house less than 10 square meter, the windows are closed all day in summer. If you open it, she will close it. I'm too lazy to compare with them. I will go back to the dormitory in the evening and go to the library the rest of the time.

Do not like hygiene. After eating takeout, you can put it under the table for several days, the seats are full of garbage, you can take a bath once a month in winter, you don't have to change clothes, and so on. Even if others say it a thousand times, he still looks like I am very comfortable, but the people in the same dormitory are so helpless.

Someone who always borrows money from you or brings food but never pays it back. If it's once or twice, you can bear it, but what about people who always ask you to bring food or borrow money and don't pay it back? Should others support you? This is too much. I can't take it anymore.

Love to flatter. If the school has any activities to reward and evaluate outstanding students, please please the teachers in our class immediately. Other people in the dormitory will share some school activities, but she won't share them with other people in the dormitory. She will only participate by herself and show off in front of others after winning the prize.
