First of all, if your roommate is lazy, get along with him with an acceptable attitude. Everyone has his own strengths and weaknesses. Some people just don't like to move, which is understandable. However, it doesn't matter if someone is lazy, but it's not good to be lazy to others. Let me explain, that is to say, some people look lazy and say they are lazy and helpless. However, for such things as fetching water, they seldom need help from others. When the floor is high, they take down the kettle in class, fill it with water when they come up, and then lift it up. This is really lazy, but because they are lazy to think of ways, this is a person with shortcomings, but they try to make up for it.
Secondly, if you think you can't accept such people, don't make friends. Not everyone in the dormitory will be friends. Some people don't want to fetch water, so every time someone else goes to fetch water, they say, help me, thank you. Such people may be annoying. Where do you sit, watch a play and play games? Why do you need others to do these things for you? It is understandable that you don't do it once or twice. It is normal to be lazy once in a while. But if you do this every time, it will make people very angry, then you can choose to refuse at this time.
Similarly, if you meet an excellent roommate, don't take it to heart if it doesn't affect you much. Dormitories are all small things, even big things can roll with the punches. I met a roommate who prefers to use other people's things, even if he doesn't say it, it's secret. His family conditions are good and he is not short of money. He also buys big-name clothes. I can't say that he is short of money. He just likes to use other people's things, such as some laundry detergent and brushes. After using other people's products, they will say some generous words. We'll use it together the next time we buy it, and then buy it in about a month ... such people don't quite understand why.
For those who don't do what they say, I think it's wonderful, just like hitting yourself in the face. However, if such people have little influence on you, just make fun of them once in a while. If it really affects you, then do some interference. The most important thing is not to let small things move you.
