R’ Chayim Ozer Grodzenski entertained a guest during sukos. At mealtime, R’ Chayim Ozer went outside to his sukah, but then said that due to his ill health and the suffering he undergoes in the cold weather, he was not obligated to eat there. The guest told him that since cold weather did not affect him, he felt obligated to eat in the sukah.
A few minutes later, R’ Chayim Ozer joined his guest in the sukah to eat the meal. The guest was surprised to see him and asked R’ Chayim Ozer why he had changed his mind.
R’ Chayim Ozer replied “Suffering does not free one from the mitzvah of entertaining guests.” ~ R’ Zelig Pliskin
