I sent my coworkers an email yesterday telling them I wouldn't be on Monday, as I'm being raptured on Saturday. I told them someone would need to look after my cube, customers, and take over my decorating the cubes for bdays that I do.
I've printed up a "good-bye" letter that I will leave on my monitor.
And I plan to come in on Monday, but work from the 3rd instead of 4th floor, and leave my cube abandoned for most of the day, as a joke.
