Rush-Hour Rescue

I was driving at the height of rush hour on the first really cold day of winter. Some sort of construction bolt was sticking up in the street, and I heard my front tire rupture. I had no idea what to do. At the next stoplight a young man knocked on my window to say that if I pulled over, he would change my flat tire for me. And he did, despite the bitter cold and risk of getting tire grime all over his clothing. We exchanged business cards, and I sent him a Starbucks gift card and a thank-you note. He then e-mailed me to thank me for thanking him!
