What is the psychology of the person who suddenly sent you a message for a long time?

If someone you haven't contacted for a long time suddenly sends you a message, 80% of them may want to ask you for help, or they may just want you to leave with the money.

There are many such situations around me. Some friends said that some people in their circle of friends did not interact quietly in their circle of friends. Suddenly one day, they sent a message to themselves and asked what they were busy with recently. A friend thought the other person missed him and asked him how he was doing. As a result, the other party sent a message saying that they were getting married recently and hoped that their friends would attend the wedding.

If you meet someone you haven't contacted for a long time and suddenly send you a message, you can reply according to what he sent. If you ask for help or let you take part in some activities you don't want to go to, you can refuse.
