A number of years ago there was a tragedy here in town when a lady was Niftar very suddenly. Her husband left for shul and returned to find hatzolo and ambulance trying to revive his wife, to no avail.
Reb Nosson Tzvi Finkel Shlita “happened” to be in town at the town, and went to be menachem avel. He came in and sat down. He did not speak a word. After a few minutes silence he said Hamokoim yenachem etc and rose to leave. R’ Ahron Chodosh shlita said “az der rosh yeshiva red nischt, maint as es iz nisht da vas tzu zagen” meaning if the rosh yeshiva doesnt speak means there is nothing to say.
As I have said before, I have a motto “if you have nothing to say, dont say it”!
