My friend's friend was telling a joke and everyone laughed. Why can't I laugh?

People will have different ideas in different situations. For example, you can laugh when you are in a bad mood.

The above is just one reason.

Another reason is your own reason. Maybe you think it's funny.

According to the information you provided, I believe it is the first case.

If you want to get out, think about what unpleasant things you have encountered recently, what difficulties and troubles you have encountered, and then try to solve them! In fact, your friends can help you in some ways, so talk to your friends more. Friends are really important!

I hope I can help you solve a little bit! Just to help you share a little.
