I worked an overnight shift (8 p.m. to about 6 a.m.) for a few years. In fact, I was working it while I dated my wife and after we were engaged. I worked nights all week; on Friday mornings I would go home, daven, sleep an hour or two, then drive to NY for Shabbat. My kalla would leave me a shopping list, so I’d walk down Avenue M and pick stuff up. I took a nap in the afternoon with the family I was staying with, then walk to the subway to meet her when she came home from work. We had a normal Shabbat and Sunday, then I’d drive straight to work from NY on Sunday night.
During the week I would find an early minyan, then go to sleep. I also tried to take a nap in the afternoon. My eating schedule during the week was breakfast in the early afternoon, dinner before I left, and a lunch type meal in the middle of the night.
What is a capstone?
