One summer I got a ridiculous number of flat tires in my 300,000 mile jeep.

One of those happened in a heavy rainstorm. The ground was soft, and I don't know why exactly, but I couldn't get the jack to lift the jeep high enough to lift the tire.

I was on a country highway near my home, with no cell service and maybe one car every ten minutes. I tried a few spots, even just halfway in the lane--I was afraid, though, because the rain limited visibility for other drivers.

A man pulled up behind me in a Subaru. He wasn't local; he had come from Tennessee to paint a local scenic spot. He not only lent me his jack, but he got out in the pouring rain and helped until it was done. We both had raincoats, at least.

He said that just the day before, he had a flat of his own, and someone stopped and helped him solve some problem he couldn't get around, too.

I doubt that's the nicest thing a stranger ever did for me, but I sure appreciated it. Stopping and helping may be a small kindness, but it can feel like a miracle to the recipient.
