Proof is easy. Take a picture of the Kitchen/table area with some jigsaw puzzles and magazines on the table. Take a picture of Rob in the drivers eat while showing the unique black line in the wood floor. Put a water bottle in the picture and have him holding the steering wheel this time. Lastly, toss some soap and shampoo in the shower and take a picture now that it has been used. And, yes, please move the squeegee.
