SMS cares about girls, and girls reply. Mm-hmm. I see.

In fact, the mentality of answering this question is nothing more than these two situations. One is that when someone answers your question or receives your message, they can answer or know. Explain that people have understood your meaning and agreed with you; This is just a way to respond. Everyone has this mentality, and there is nothing wrong with it.

The second situation may also exist, that is, someone chats with you, and if the other person doesn't attach any other language, the ending is mm-hmm or know, ending with a period. Maybe people don't want to talk to you anymore or it's not convenient to talk again. If you have nothing else important to do? Please end the conversation as soon as possible. Sometimes this situation may be a euphemism for refusal; In fact, each of us should learn to respect each other when interacting with others, and respecting others is also respecting ourselves; Don't force anything, and don't force anything. Everyone has his own difficulties. It's better to know more.
