I came home one day for lunch and the landlord was tying his bumper to a huge clump of Pampus Grass. Being familiar with that sort of thing, I told him it wasn't going to work. He dismissed my concerns. When I left for work shortly thereafter, he was trying to untie the rope tied to his now badly bent bumper. He didn't want to talk about it. The Pampus Grass was unfazed.
