Maybe it's because you just entered junior high school, no one knows anyone, and your classmates all have the same idea with you, so they will show their best, so they are all very easy to get along with at this time. At this time, you should take the initiative (chat with each other, if you can get along), but you should pay attention to making friends with people of your own personality, be good at observation and be careful in making friends. Maybe after a while, you will find that you are not suitable to be friends. At this time, you can point out the other party's mistakes, and it is best not to break off diplomatic relations easily (cherish, cherish friendship only when you lose it). ....
Besides, regardless of your academic performance, some students are not very good at it, but they are good friends worth making (I have met such friends). Of course, if you get good grades, you can help each other.
