That’s true but it depends. I had been trying to keep more normal hours lately. And since I didn’t sleep today during the day (and had a very busy day obviously), I had expected to go to sleep at a normal hour tonight.
But I ended up having to take care of a drunk Yeshiva Bochur who had passed out at the busstop and getting him back to his Yeshiva in Yerushalayim (long story), so I decided to go to the Kosel while I was there, and almost missed my last bus back, which would have been REALLY BAD because even if I found a place to sleep in Y-m, I doubt I would have found a Megillah reading at that hour (which I would have been chayiv in if I slept over), but BH, there was still a bus. So I just got home about an hour ago, and that’s why I’m still up.
