A poem that describes a person who forgets to listen to it is a poem that should be forgotten when he hears it, but who would believe it.

the original text is a casual phrase of the speaker, and there is nothing to rely on. When you hear it, forget it. Who knows it? Remember, remember, but know that it is not easy to make friends.

This means that the speaker is unintentional, and the listener is intentional. The speaker doesn't remember what he said at all, but the listener has written it down deeply.
