I always send messages to my colleagues and classmates on holidays, and I usually have contact, but some people just don't reply to you, which makes me very unhappy?

It is normal to send messages to colleagues or classmates on holidays. But some people reply, and some people reply. People who don't send blessings and don't reply to WeChat are not rude, but feel that there is no need to send them and return them. Personal personality problems, a WeChat group, are more or less heart. Or forwarding others' words, without writing some cordial greetings yourself, feeling is a form. Therefore, it is not a polite question not to send you a blessing, but a question whether you think it is necessary. Don't worry about whether others have a good impression on you. As long as you are sincere to them, they will not care about these false names.
