Q. Re- question 1933. Is there also a hetter not to stand more than once or twice a day for any elder?
A. Rema (Y.D. 244: 16) rules that a talmid should not stand up before his rebbe more than twice a day. This reflects the teaching of Talmud (Kidushin 33b), that the honor given to a human should not surpass the one given to Hashem, whom we honor every morning and night, (when reciting the shema – Taz). However, the Rema adds, that if others are present, since they may not be aware that one has already stood twice before his master, one should stand again.
Horav Shlomo Miller’s Shlit’a opinion is that the same should apply to standing before an elderly.
