A man sent a good morning message for four days in a row, but suddenly stopped sending it today. What is the reason?

A man sent you good morning for four days in a row and suddenly stopped sending it today. Actually, it's not interesting. He said hello to you for four days in a row. That is to say, he has time these four days, so he may be busy today, so he didn't send it to you today, or he forgot to send you good morning today because of other things, so you don't have to analyze it too much. Sometimes a man wants to pursue you, so he will also use some tricks. He will send you good morning for four days in a row, then stop for a day or two, and then continue to send it to you, and you will be impressed by him. It can be seen from your question that you noticed the problem and your eyes have a certain impression on him, so he achieved his goal.
