Why are some seemingly joking words often the most true?

Why do you say something that seems like a joke, which is often the most true? This question is actually very common and very real. Why do you say that? Let me talk about my personal views for your reference only.

Why do many words seem to be jokes?

In fact, many words are not taken seriously, but when you go back and savor them carefully, you will find that such words were actually said on purpose, but you would think it was a joke under the circumstances at that time. So what is the moral of this joke? I may have told it to you on purpose, but I can't say it directly, so I said it in a joking way. This way is acceptable to everyone and will not be deliberate. If the parties understand, they can continue to talk. If the parties don't understand, they can laugh it off. So many words seem to be jokes.

But why are these words the most true?

In fact, these words are very true, which is true, because there are many seemingly joking words. In fact, I want to express my inner words with the most authentic attitude, because I don't know how to say them, so I will use seemingly joking words, but these words are my most authentic inner words. These words may only be understood by the parties and recipients, and other onlookers may have heard them and won't take them seriously, but they will know how true they are when they say them.

Problem summary

In fact, seemingly joking words are often expressed to someone, just to see if they can understand, so no matter which way, the final result is to tell them. As for whether the other party understands or plays dumb, that can only be the case. Seemingly simple words are intended to be expressed to the other party. The above is my personal opinion, for your reference only.
