Leave the drunkard alone, he will fall by himself/ Do not try to convince an obstinate man he is wrong, he will find out himself !
The end of all drunkenness is to be drunk and to fall. In a question: Do not try to explain to a person who stubbornly refuses to understand, life will teach him what he needs to learn.
("And what is the difference between the hour of the day? Rava said, "The fear of the Torah is sharp, and the fear of the sakhina is sharp. Abaye said: "Tafesh Tirus Amata" - one who is abhorrent to Yahuweh. Rav Chisda said: "He who is knowledgeable in the revelation, he is abhorrent to himself" - Shabat Lev a.a.)
