Anyway, I decided it would be a good idea to pick up a pair of boots in his size to keep here in case it ever happens again. I found a nice pair of Timberlines at Good Will and picked them up for a couple of bucks.
Tonight a stranger knocked on my door and asked if he could abandon his car in my extra driveway. Since another car had already crashed into a parked car across the street, I said sure and asked if he was going to be able to get home. He said he was in for a long walk in the snow but thought he'd be okay. Then he looked down at his feet in a kind of sad way and I noticed he was wearing dress shoes. I offered the boots and it turns out they were a perfect fit.
Hopefully they will get him home without frostbite. He'll return them when he picks up his car.
