Friends send good morning and good night every day. Does this kind of person have mental illness?

Generally, such people are more self-centered and feel lonely, so they always talk to themselves or expect someone who knows them. If they don't meet them, they will feel lonely and have no bosom friend.

Personal feeling is idle. Few busy people do this every day, at least they are mentally empty. Busy people don't make friends, rich people show off, business managers make management rules for brainwashing, vain women make famous brands, and they make chicken soup that hurts their hearts. Their parents' hair is all kinds of chicken soup, as well as health care, diet and fake news. People who exercise are all muscles, and mothers with children bask in their babies. Friends who travel in the sun, as well as those who open online stores, are all advertisements, and the circle of friends is very chaotic.
