Get the heck out of my neck of the woods, you malingering precipitation. Don't you know we're having a party tonight, and a fair amount of the party is planned to be held outdoors? How fun is a bonfire in the rain? Or a bounce house? How about SCAVENGER HUNT? How we gonna do THAT if there's a chance of also getting costumes wet and makeup runny? Why, that's not much fun at all.
So, shoo, rain.
And take this frigging headache, cough, and wheeziness with you.
