I just wanted to say that your father obm goes back to my childhood years. He was my hero.
Whatever and wherever I turned your father was there.
Who can forget your father running on a hazalah call with his long flowing beard trying to catch up?
In 770, farbrengens, Kos shel brocha hakofos etc etc. He was an important figure in Lubavitch.
I’m sure the rebbe gave him a big shalom Aleichem in gan eden!
Only simches in the family,
Shlome Friedman
