Someone in a classmate's family died. I don't know. I was laughing while talking to others in the classroom, and she yelled at me. What should I do?

What to do if not! The problem is that if someone dies in his family, it has nothing to do with the legitimate rights of others. If you say you don’t know, then you are not sorry for him at all. Your classmate is really weird. When someone dies in the family, should the whole country observe a moment of silence? I don't mean to be disrespectful to the deceased at all, but your classmate is taking it too far. As long as you apologize and do it, that's fine. You haven't done anything wrong, so there's no need to compromise
