Speaking With Silence:
Rav Menachem Mendel of Vorka zy”a spoke very little. Even when he met with Gedolei Hador, he usually remained silent. They understood what he meant with his silence and they would “converse silently.”
He once met with Rav Elazar of Kozhnitz zy”a, and they sat together for a full hour without saying a word. They then said, “We have spoken for long enough!” And they went on their ways.
