Man neighbors suck sometimes. Opinions?

Couple across rhe street use to let their little dog out 2 or 3 times a day. It would walk across the street and crap in my front yard or in my driveway. I asked them on a couple of occasions to keep their dog on a leash and not allowed over to my yard to crap. They wouldn't do it. They had a real lovely driveway that they kept painted asphalt black so that it just shined. One day after the dog took a crap in my driveway I picked it up with a shovel walked over to their shiny black driveway and drop the pile right in the middle of it. After that they put their dog on a leash when it was time for it to crap
Awesome, but i woulda flung it at their front door myself.
