Why am I always laughed at?

I think you are an introverted boy! From what you said above, I guess you are still a tolerant student. In fact, you did a good job, only in your attitude towards them. You are too tolerant of them. Some people are like this: they will take your tolerance for them as their indulgence. Have you ever heard of this sentence? It is said that one should not be too weak. Some people just like bullying honest people. If you meet such a person, you should be tough and show that you are not a bully. You should show that you are a capable, self-respecting and tolerant person. You must show your ability and don't be bullied.

Besides, you said you would clean the dormitory yourself, which is not good. If you do this, people will think that you are born to clean the dormitory for everyone. I suggest that you don't have to clean as long as you are not on duty.

In addition, you can try to communicate with them more. When they talk about a certain knowledge, you can also tell them what you know about it, and let them know that you are not a person who can only learn, and you are knowledgeable, just like them.

Don't be afraid, as long as you do something meaningful, let them think that you are also a great person and a self-respecting person. Everything will be fine in this way. Give it a try! ! ! I wish you can do it well! ! !
