Sometimes, when you get off a crazy long shift at work, it's fun to drive around in the dark and rain and look for teenage girls that aren't where they were supposed to be. Or where you think they were supposed to be. Even if neither they, nor you, really knew or had established where that location was. Hence the driving. Sometimes, on Halloween, it's fun to drive every block in town (which is luckily only ten blocks here), and accost every group of nearly adult sized humans you run across in the dark and the rain. It's also fun to interrogate these shady groups about the whereabouts of certain teenage girls. And even if they don't know anything about any girls, it's fun to make them feel weird about being accosted in the dark by a mom in a car.
The thing about dark and rainy nights, when all kinds of shenanigans are happening in all kinds of dark alleyways, even if you've worked ten hours, you drive around and locate the girls. And then you invite all of the hooligans over to your house. Because, better there than Someplace That You Don't Know About. And then, when they get bored with the 6 cubit feet of popcorn that you made, and the scary movies, you drive them home so that nobody gets lost in the dark and rainy night or become prey to the various shenanigans.
And maybe, if you're lucky, sometime around midnight, on a dark and rainy halloween, when you know all of your girls, and probably a few others, are giggling safely upstairs, and the dark and the rain and the shenanigans are locked outside, and the traditional Tire Fire on the hill is contained and won't burn down the neighbors houses, and you know this for certain because you went and checked for them, and then went back to tell them for sure, and the dogs have had their fill of dropped M&Ms and popcorn, and you've picked up the house at least 12 times, maybe you can go to bed and get a few hours of sleep before you go to work again in the morning.
This is why Halloween is fun. And teenagers. And traditions.
