People who are not afraid of nonsense are afraid of serious nonsense?

Yes, just ignore the people who talk nonsense. But people who talk nonsense seriously, you don't even know whether what he said is true or not, and some just feel that what they said is right, but they don't feel that what they said is wrong at all. I'm afraid it's difficult to reason with such a person. I have met such people before, but all the important things can never be said well, so I should say them in a joking tone. Every time I say something unreliable, I'm serious. No tone. I have no idea. His work and rest are really tired.
