Someone recently brought his son to R’ Ahron Leib. He held two yarmulkes in his hand, one black velvet, the other seruga. He asked R Ahron Leib, “Is there any difference between these two?”
R AL responded, “No difference.”
The father then said, “Well if they’re the same, then is it fair that my son just got thrown out of his yeshiva because he wore the seruga?”
R’ Ahron Leib responded, “If they’re the same, why can’t he wear the black one?”
