If you're going to go to an overnight Girl Scout Leader event, you're probably going to have fun. If you're probably going to have fun, you'll probably be too jazzed up to go to sleep. If you're too jazzed up to go to bed at a decent hour, you'll probably end up staying awake all night with the other troublemakers. If you stay awake all night with all of the other troublemakers, you'll probably bottom out early on the next morning, and be VERY cranky and sleepy.
It's sort of a "If You Give A Mouse a Cookie" kind of prophetic, isn't it? A self-fulfilling prophecy that shouts, "Hello, Captain Obvious!" at the world.
I'm going to bed. Wake me up tomorrow.
