Popa Bar Abba: If its true that babies cry because they are sensitive to ruchniyus, why do they always cry in shul? Why do they cry by chupah’s?
Da’as Yochid: Good answer!
Mashiach Agent: Whether that’s true or not, that’s very profound! However, I always learned that when the malach taps a baby over the lip, the baby forgets everything from before it was born.
