Seeing his arm, waving like a windshield wiper out of his enormous truck, woke me from my buoyant reverie.I was singing along to “Beautiful” by MercyMe, my daughter by my side, and admiring the bright sun, fall colors, and cornflower blue sky when we slowed to make a left.There was unending traffic coming from the other direction so as I waited to turn, I looked into my rearview mirror and noticed several cars backing up behind me. That’s when I spotted the truck driver with an infuriated face, making sure I saw his middle finger pointed high in the air, loud and proud.
