common > especially in regards to halacha such as not saying a kaddish
common, let’s be positive (thanks again, Mrs. Syag) ! we are absolutely on the same page.
I did not have azus to disregard halakha of tircha in such extreme situation, when seeing my fellow Jews showing such mesiras nefesh, trying to keep their hands and feet warm, while still holding a siddur. Not one left early. Not one tried to move out of shade into the sun at the expense of neighbor’s place. Some of them, relative after- or in-college youngsters, who probably never experienced such challenge before. If you would have seen such nachas with your own eyes, you would have rachmonus on them too, as rachamanut is said to be a sign of Jewish nations as taught by “Moshe Rabbanu and Yshua ben Nun”.
Still, waiting if you have asked your Rav (when explained both the kaddish and the freezing part) and whether he thinks differently. I would be interested to hear his arguments.
