Your dust is killing my grass

Okay, I just have to post this because at the time, when the incident happened (over 2 years ago) it really ticked me off.

So at the time that we bought our lot and started clearing the trees off and grading it, it hadn't rained in a long time. The ground was exceptionally dry which made the grading process really dusty. Anyway, one evening Paul happened to be at the lot and our backyard neighbor came out and talked to Paul. I don't recall the exact words he said, but they were in essence...All the dust you're creating is killing my grass. That was it. No "Hi, How are you. My name is so-and-so". Just your dust is killing my grass. Now the picture above is to show how ironic that statement was. His "grass" is nothing more than weeds 2 years later. I have never seen them open up their blinds to the back of their house to look at his grass he cared so much about. He doesn't even mow his own lawn, he hires people to do it for him! Now his precious grass which he has so lovingly cared for is now infested with nasty weeds and is killing our grass.
