I won't do that!

This morning when I did the walkthrough of my building, I found dog poop on the roof. Not on the deck, mind you, but on the roof. Meaning that someone was enjoying there sunny weekend day on the roof with their dog and when little Fido had to do a poo, they were too lazy to take them outside....and then too lazy to clean it up. And I'm not doing it. It's going to stay there until the next torrential rainpour and I hope everyone can see it so they know how lazy their neighbors are.
