Burying the Dead
One time i couldn't get ahold of my father all day. When he finally got home i asked what had happened as his hands were blistered and clothes covered in dirt. He said that he went to that big funeral of a famous person that day he had known. While the conservative rabbi had done a big ceremony. At the plot very few people came so he officiated there. He dug and covered the entire grave himself as that is supposed to be done by Jews. This wasn't the first or last time he did this for another yid.
Anytime he came home like that i asked who had passed and went to read their obituary.
