What is the mentality of those who don't reply after receiving the New Year message?

These people generally don't take it to heart, thinking that this kind of news is all mass.

It doesn't matter if you don't go back. I don't want to spend time going back, which saves this slightly troublesome thing. It is very likely that in real society, people are too tired to socialize on the surface. Except those who are very close, people should maintain a more polite state, which may sometimes go against their original intention. When I got home, I completely relaxed and didn't want to be busy socializing, so I saved trouble on the virtual map.

Don't take this kind of thing too seriously. Judging a person depends on how you get along on weekdays.
