Go your own way and let others talk. Roommates taunt you that you can't eat grapes and say that grapes are sour. She is also afraid that you will go to the library to study and be better than her in the future. Don't care too much about other people's ideas and opinions. Even if she goes a little too far, we still have to follow our hearts. There's no harm in going to the library. You can't change your mind just because someone said a few sarcastic words. Is this too weak? Only when you know what you think is yours, no matter what others say, she will regret it later. As a roommate, don't care too much, it will be a bit awkward to get along with each other in the future.
Don't pay too much attention to what others say. Books are for yourself. Your roommate may tell you so, because he can't see you become excellent. She said she, just go to the library as usual, just ignore what she said. After a long time, she will find it boring. If you really can't help it, you can also say a few words to vent your anger, and you can also extinguish your roommate's arrogance. What's wrong with studying is better than eating, drinking and having fun every day.
Sometimes caring too much about others' opinions will hinder your progress.
