I'm on a smile & wave basis with an Amazon delivery contractor who nearly hit me a few months ago. I chased him down to fuss about rolling through a stop sign and nearly hitting me. But I could tell he was genuinely surprised and sorry. It was a new route to him and he had glanced down at his GPS navigation doodad. Because he seemed sincere I didn't file a complaint, just shook his hand and let it go.
Since then I've seen him making other deliveries. He'll beep and wave. I wave back. Not a bad resolution.
This was just a week or so before the coronavirus pandemic suddenly changed things. And before some other tragic news incidents locally and nationwide, where conflicts between strangers quickly escalated into violence. I don't ever want to be part of that.
