Yeah, I'm smart

Today I woke up for my 9:00 class as usual. I'm sitting in the room wondering why no one is there. 9:00 passed, and I'm still the only one sitting there.

Apparently, today was Yom Kippur, and the 9:00 professor is Jewish and had cancelled class. And apparently he had made many announcements during the week about it, but I happened to miss all of them.
