My friend sent a message to Weibo that you were out of breath. Are you kidding? Should I reply to her? How to reply

A friend sent a message saying that you were out of breath, of course it was a joke! I'm disappointed in you because you fell silent when chatting with her. If you don't want to talk, you can find an excuse to say that you are busy and talk next time, instead of not returning to him when you see the information. If you care about him, just say, Oh, I'm busy now, and I don't have time to talk to you.
