There is a girl who always imitates me and compares everything with me. What should I do?

To put it bluntly, I look down on you. You must fight for it. But you'd better be yourself. It's not good to have people like you in the dormitory. That means you deserve to be imitated. Don't take your temper on others. She can do anything she likes. Just don't care too much or find a time to talk to her alone and find out the problem. Otherwise, the cold war will end on both sides. I suggest you take the initiative to talk to her. it's not a big deal
