A classmate always uses me, only looks for me when she needs me, and always asks me to accompany her

Is it the kind of relationship that seems good on the surface? If so, when she calls you the next time, pretend to do your homework, and then she calls you you and says to her, "I have something to do today, I can't accompany me."

Then say it once a day, and over time it will be fine (it will be useful in a week), and if you still can't get rid of it, just say that I am not suitable to be friends with you.

Me too... But I told him, I don't want to go, I still have homework to write, you can go yourself, or you go first, and I'll look for you when I finish my homework.

You let her go on her own, saying you don't want to go to the toilet, and if she forces you, you just refuse.

It's locked today. I don't have the key.

You said that the teacher had something to do with you.

In the way of others, return the body of others.

There are too many people like this around.

Just say you go first, and I'll come later.

Dare to say no, and you will improve.
