I do not remember who this story applies to.
There was a rebbe who lost his son due to an illness.
Another rebbe went to be menachem avul and told him
“I am jealous of you.” Everyone’s ears picked up.
How can a person say such a thing to someone who just lost his child?
The rebbe went on to say “I once had a beautiful daughter, who had a daughter of her own.
They were both killed in the holocaust and I don’t know when their yartzeit is, nor do they
have a burial place for me to go visit”.
The other rebbe answered “You have comforted me.”
