Don't you hate it when you're at work?
Wait, that's not the end. You're at work — on the bottom floor, because that's where the snack machine is — and you decide to use the restroom. The cleaning lady is in there, with her cart blocking the door. So, you take the stairs back to your floor, the sixth, because you haven't met your daily stairs quota and have to work off this latest snack. Coming around the corner to this restroom, panting from the exercise, you find the cleaning lady is now there, blocking this door!
I hate when that happens.
