come on tell me!

Imagine that you encountered a madman and claimed in front of you that he was a fish, and that we were all fish.
Turks fight it? Turks turn to him to convince him that you do not have fins? Turks tell him explicitly what you think? come on tell me!
If you tell him the truth, and only tell him what you think is true, then you agree to go into a serious discussion with a madman, and you are crazy yourself. This applies exactly to the world around us. If you insist on telling the truth frankly, it means taking it seriously. Taking something seriously wrong means that we lose all our seriousness.
I have to lie so I do not take madness seriously, so that I do not get mad too.
