A guy who just found out he won the $27 million jackpot in a German lottery responded to the news by saying, “I don't have time to chat right now. I'm late for work.”
Although it comes off sounding odd, I can understand what he means. If I won a lottery, no matter how big, I would still go into work that day (and for the next little while) because I like the people I work with, and I would feel bad for them if my sudden departure causes them undue stress.
No doubt, I would give my “two weeks notice“ that I intended to leave and would leave sooner than that if I could, but I wouldn't just “not show up” again. There's no excuse for doing that to people you consider friends.
