Of course, this thread needs the famous story with R’ Yoelish. He had a good relationship with R’ Moshe Sherer zt”l. One day a chossid asked him why he didn’t push R’ Sherer to grow a beard. The response was, “When R’ Sherer gets up to Shamayim, they will say, R’ Yid, where is your beard? When you get up to Shamayim, they will ask, R’ Beard, where is the Yid?”
Just to note, I’ve seen the story with R’ Sherer zt”l, Mike Tress zt”l, and R’ Leib Malin. I have no clue who it really happened with. I just wrote R’ Sherer this time because he was the one who popped into my head.
