Driving to daycare today, I got stuck behind someone poking along at 25 mph in a 35 zone. We came to the light, and of course they turned the same direction I was going.
Grr.
Soon we came to a 20 mph school zone … and they sped up to 30.
Huh.
Afterward, as I pondered deeply on possible motives (clueless? or just angry at third-graders?), I was reminded of the words of Henry David Thoreau in Walden.
If a man does not keep pace with his companions, perhaps it is because he hears a different drummer. Let him step to the music which he hears, however measured or far away.
Except, like, don’t be a dumbass.
Wisdom, perhaps, for us all.

That’s the worst! Inconsistent drivers make me crazy. …we have a lot of them in Atlanta
