Just got a call from a guy asking me if I broke the window on his house. He said when he got home his window was broken and he had found the guilty rock which happened to be laying in a rock bed in front of the house. It was a double paned window but he said only the outer pane was shattered. Heres my problem. At no time does my chute face the house when Im mowing. Also I cant imagine a rock coming out of a mower and shattering the outer pane of glass but not making it through to the second pane. Im a little leary on paying for it but I told him I would come by tommorow morning and take a look at it.
