Rabbi Yochanan was dozing off while his two students discussed their questions. However, their answers were based on logic. For example, they asked, why are Holidays in Babylon more joyous than in Israel? Because they are poor and reserve celebrations for the Holidays, and so on.
At that, Rabbi Yochanan awoke and said, "Children! If something is clear, certain, and wise, say it. If not - do not say." Then he gave the Torah explanations. For example, the Holidays in Babylon are joyous because they were not included in the curse of "Your new moons and Holidays My soul hates - says the Holy One." That applied only to Israel but not to Babylon.
