The purple foot

People are strange. I'm often reminded of that, although it usually hits me when I'm at the mall.

On Saturday, we were driving back from Home Depot (personal note: NEVER go to Home Depot on a gorgeous Saturday afternoon, because everyone else has had the same gardening urges that I had.) and in the car in front of us someone was sitting with their foot out the window. I've seen people do this before, especially on nice days, but the unusual thing was that it was just one foot and on this one foot was a purple sock.

Now if you're going to roll down the windows and enjoy the breeze between your toes, wouldn't you remove your sock? They didn't. So we followed the little white Ford Escort almost the whole way home pondering the deep philosophical meaning of the purple foot.
