As you see from the comment to my last post, the author of The Law of the Garbage Truck has been found, David J. Pollay. To the law, I add this pledge, also authored by Pollay:
The No Garbage Trucks!™ Pledge
I do not accept Garbage in my life.
When I see Garbage Trucks,
I do not take them personally.
I just smile. I wave. I wish them well.
And I move on.
And I do not spread Garbage to others.
I am not a Garbage Truck!
