How to treat the phenomenon of sending a message to ask a teacher a question without answering it?

There are many such phenomena. Learn to be considerate of teachers. Maybe the teacher didn't see it because he was busy, or he saw the message you sent when he was busy, and then forgot to reply to you. So don't have it. The teacher doesn't want to answer my question. The teacher doesn't like my idea. We should keep a good attitude to face these things.
