I sent a text message to greet my classmate yesterday, but she didn't reply. Then I clicked on her circle of friends and this appeared. What should I do?

First of all, your classmate is not a WeChat merchant, otherwise she would not set up a background wall but block you in the circle of friends.

Secondly, you send a message to greet her, but she doesn't reply. Your circle of friends blocks you, indicating that she is online, and she doesn't reply to you online, indicating that she doesn't want to talk to you.

Finally, keep your distance. Don't provoke if you have nothing to do. This attitude is obviously rejected by others, and it will be boring for people to put cards on the stand.
