Twenty-three positions in a one night stand

As I was driving in a nice neighborhood on the way to work a few Fridays ago, I happened to glance over to the houses on my left. An elderly woman using a walker was making her way slowly up to the pathway to a large house with a manicured lawn. The car that had just dropped her off was a brand new Buick that contained an elderly gentleman. Even though the woman was sporting clothing that looked expensive, something was a bit off. Her hair was NOT carefully coiffed, and the orange/red lipstick that most sophisticated ladies of her age and stature wear was noticeably missing.

Then it hit me. She was doing the old lady walk of shame!
