A person always doesn't return your messages.

There are many possible reasons why a person does not return messages. Here are some possible reasons:

Busy: Maybe this person is busy with work, study or other tasks and has no time to reply to messages. In this case, you can try to wait patiently for a while until they have time to reply to your message.

Personal problems: this person may face some personal problems, such as physical discomfort, bad mood or family conflicts, which will make them unwilling or unable to reply to your messages. In this case, respecting each other's privacy and space may be the best choice.

Technical problems: sometimes it may be because of technical problems that the other party can't reply your information in time, such as mobile phone battery, network connection problems and so on. In this case, you can try to contact each other in other ways, such as telephone, email or social media.

Not interested: This person may not be interested or want to reply to your message. Although this may be frustrating, respecting each other's wishes and decisions may be the best choice.

Forget to reply: Sometimes, people may forget to reply to messages. In this case, you can remind them to reply to your message so that you can get their reply.

In short, there may be many reasons why a person does not reply to information, so we should respect the privacy and decision of the other party and consider using other contact methods when necessary.
