How to comfort people in a bad mood

First of all, you need to know the reason why the other person is in a bad mood. Even if you don't know why, you can get to know each other by talking to each other.

But when comforting others, you don't need to directly tell the reason, you can directly take the other person to do something that the other person likes.

For example, take each other out shopping, or travel together, or take each other out for a big meal. In short, when the other person is in a bad mood, do something that the other person has always wanted to do, but has never had time to do it.

After playing for a day like this, my mood will be much broadened. Even if I am unhappy, I will feel much better after playing for a day.
