Maybe a casual word can hurt a person.

In fact, some people say that the speaker is not interested in listening. In fact, there must be a saying that inadvertently hurt a person. There is nothing wrong with the speaker, but it hurts the self-esteem of the listener. After all, there must be a lot of words that the speaker overheard, so I think a word that I said inadvertently or unintentionally will hurt someone, but sometimes I have to think about it from another angle, and you know that others didn't mean to say such things. And I can't be too serious about this. After all, sometimes it's not good to be serious and joke. You should know when what you hear is true and when what you hear is a joke.
