When a rich new neighbor bulldozed part of my grandparents’ land to build a driveway—without permission—Grandpa Lionel tried to reason with him. The guy shrugged it off and hung up with a smug “sue me.”

But Grandpa didn’t need a lawyer. He had Patrick, an old friend with an even older, rusted F-150.They parked the truck perfectly across the stolen driveway—on Grandpa’s land, of course—with a note: PRIVATE PROPERTY. TRESPASSERS WILL BE REPORTED.
