I once got laid off, at the company's Christmas Eve party. As I was walking in, my supervisor pulled me aside, let me know that the company was letting me go.
Yeah, that Christmas party was a downer. :/
The next day, I was having Christmas dinner with my parents and my sister. My sister asked me how work was going. "Got laid off yesterday," I said; I hadn't told anyone yet. Kinda cast a pall on the entire dinner.
