Rav Henoch Leibowitz and the Lowered Mirror
Rav Henoch Leibowitz stood on tiptoe to check his tefillin in a small hallway mirror, until a bochur quietly put up a lower mirror for his Rosh Yeshiva.
HaGaon HaRav Henoch Leibowitz, zt”l, used to put on his tefillin in his office. When he would come downstairs to daven in the beis medrash, he would walk down a hallway that had a small mirror attached to a towel dispenser. The Rosh Yeshiva would stand on his tiptoes to check his tefillin in the mirror. A bochur in the yeshiva noticed this and installed a small mirror lower down to enable the Rosh Yeshiva to check his tefillin comfortably.
