You know the kind of windows where they say they will be there between 8 am and 12 pm. And you are firmly entrenched in your summer sleep schedule which means you don't fall asleep until 1:30 am at the earliest. But you have to get up, because the window is 8 am to 12 pm. So you're tired and cranky and it is now 11:30 and they will probably show up at 11:59. Ugh.
