Wechat, how to reply if someone sends a mistake?

Say sorry if you send it wrong, or say nothing if he sends it wrong to you. You said I often send the wrong message.

For example, did he bring you a meal? This is the message he sent you. If you are wrong, you can say that I haven't eaten yet. You can say sorry. Did you send it wrong? Or you sent him the wrong message. For example, if you send him an expression and you send it wrong, you can say sorry. I sent it by mistake, please. You said I didn't know what happened. I apologize for inviting you to dinner next time, and he will tell you yes, yes, nothing, nothing, and you say no, it's my fault. Don't worry, this meal is booked. Ha ha, ha ha ha ha.
