Don't personally know any volunteers-every-day heroes, which I guess tells you I run in inferior circles.

But I have a delightful random-act-of-kindness to report. Fierce traffic home from work, it seemed every other car was either cutting me or someone else off, or tailgating, or just being a jerk. Late in the drive I pulled up at a stoplight amongst a bunch of other cars. Guy jumps out of his pickup truck, runs past a few cars, screws in my dangling gas cover, closes the little door, and runs back to his truck before the light changed, and speeds off.
