How can I tell my good friend (same sex) not to keep texting me?

It can be said that the mobile phone is lent to others, don't send it yet ... The battery is dead. ...

Or turn around and say, I'll talk about it later. I'm busy now ...

I'm going out for a while. Forget it. ...

You find more excuses and block her a few times, and she will soon realize that she is bothering you.

If she is slow, you can stick to it for a few days and make more strange excuses, and she will understand. ...

Or you can just say that there is no money recently and there is nothing important to send. ...

It doesn't matter if we are good friends anyway.
