In just a few short months you'll wake up on a crisp Tuesday after the first Monday in November and do your part to dramatically affect the course of history. That's the day you discover your mortgage check sitting on the kitchen counter, behind the toaster, and it's already a week late (and possibly a little dark and crispy). So you'll frantically rush to the post office to send the bill by overnight mail, which will be delivered within the next calendar week, unless you express the slightest irritation at having waited in line for an hour. (Then your envelope would go in to the "special box.")
After all that, you will probably remember something about the democratic process and your civic duty to make your voice heard in the presidential election. In a moment of poignancy, you'll recall the impassioned belief of our forefathers that even a single vote can make a difference. And then you'll laugh and laugh, because of course it doesn't make a difference, silly!
But what the heck, you're already up and dressed anyway. Plus, you don't want to make up some story to your co-workers about how crowded the polls may or may not have been, depending on whether you did or did not vote, and then, on that basis, have them accuse you of making up the whole story just to take off work.
