Q. I'm a Yeshiva Bachur (after high school), staying in the Yeshiva for Purim. If my mother asked me not to drink any alcohol during the Purim seuda, do I have to listen to her?
A. Halichos Shlomo (19: 25) maintains that one should listen to one's parents and not drink.
Horav Shlomo Miller's Shlit'a opinion is that, you should drink a small shiur (amount, such as rov kos - or most of a small cup) of weak or diluted wine, to comply with the mitzva of drinking wine by the seuda.
(Provided that you are of age and healthy).
Rabbi A. Bartfeld as advised by Horav Shlomo Miller and Horav Aharon Miller Shlit'a
