I joked with my boyfriend that he didn't look like his mother. Did you pick it up? Why is he unhappy? So you can't stand it? People say that from childhood to adulthood.

Haha, yes, many people have been teased like this, such as me. When I was young, many children were teased by adults in this way. It's all good intentions, and there's no other meaning. I guess your boyfriend can't stand this kind of joke and will be angry. But if some people care too much about this aspect, don't talk about it easily in the future, otherwise they may not even have friends. Don't joke too many times for too long, he is tired of listening and is prone to some misunderstandings. In the end, it ended in discord. Don't do this.
