A boy has posted to Moments several times in the past few days, but he has deleted them after a while. What does that mean?

As for this boy, he has posted to Moments several times in the past few days, but he deleted it after a while. I think he mainly posted these Moments. Just to show that it still exists. He still has a presence. In the past few days, something may have happened to him. If something happened, it made him change. If some things touched him, he was touched by his heart. After that, he may circle these friends. Send it out. When these feelings completely disappeared, so he deleted them all after a while.
