My friend said that she was very sad and wanted to cry. How can I comfort her? Or tell her some jokes? How to make her laugh?

Girls are very entangled, and some things need to be understood by themselves. I think what you need is that no matter how complaining and unhappy she is, you should stay with her, or enlighten her more, so that she can relax and not be so tired, because she is still you!

The system actually suspects that I am watering, and there is no faucet around me.
