How to treat such remarks as "adults talk, children don't interrupt"?

Some adults don't answer until you finish. Even if an adult interrupts, we will say that you have heard it, so finish. Some adults insist on interrupting, and even if I stop to listen, I refuse to absorb what he said. The child's interruption is a feeling of never giving up, that is, when I am talking to others, he wants to interrupt. If I am sorry, he wants you to listen. Otherwise, even if you are talking to someone, he will shake you and make you listen to him. But how could adults at that time have the mind to listen? In particular, children sometimes interrupt, which has nothing to do with what you are discussing. Just because children don't interrupt doesn't mean they don't talk to them.
