Oil Stained Driveway!

It was not one day after I had been over there at the Stefanik's warning them to stop shouting so much when they fight at night, that I found two broken bottles of Ken's Salad dressing smashed on my blacktop pavement driveway that has seeped in and now leaves a great stain. How do I know is was the neighbor? Because when I went over there to hollar at them for yelling so much, I saw these salade dressing bottles sitting on their kitchen counter. Olive Oil and Vinegar flavor. Of course this can't be proven in a court of law so I am out of luck, but I know what I saw and I know know she did it.
