If a person stops replying to your messages and tells the other person what he thinks, and the other person doesn't respond, is it necessary to send them again?

Hehe, your troubles are common. Put yourself in the shoes. There are only a few reasons why you don't reply to other people's text messages:

1. I have no time to reply. I have no urgent news, but I am busy, so I won't reply.

2. I forgot to reply. I read the short message when something happened, but forgot to reply afterwards.

3. Unwilling to reply. Boring text messages, or ignoring this person and not replying.

4. Take it. It doesn't matter if friends who know too well don't return.

As the saying goes, a friendship between gentlemen is as light as water, and there is no need to ask friends to reply to every text message. If you ask him for a business trip and he doesn't reply to you, there's nothing to say. Just delete his contact information. If it's just a small greeting or a boring complaint, what's wrong with him not returning?
