Maybe he didn't want to swear for a while, and there was nothing to send, but maybe he didn't want to send a circle of friends himself, and then he suddenly wanted to send it one day, and then he deleted it if it was a little inappropriate. This is a very normal phenomenon. Some people sometimes feel that they found it for a while at the beginning, and then they don't want others to know their feelings, and then they deleted it. That's it. I'm afraid that people who care about him will be afraid, and people who like him will think too much.
