I was washing my Aunt's Mini Cooper S in the driveway while my cars were parked in the open garage. My oldest cousin (30) comes out and starts talking to me. I see her leaning on the rear bumper of the Legend and politely ask her to stop it. She simply says "No." I'm sort of surprised so I say "Seriously, can you please get off my bumper? I worked hard on this car." Mind you, this car hasn't been washed in two weeks and has seen rain a few times since the last wash. She says "It's not going to do anything to your precious car, Brett. My jeans don't even have metal on them." I honestly didn't know what else to say or do, so I just gave her a pissed look and kept washing my Aunt's car. She eventually went inside. This person is like a sister to me, so I don't know what to do if there is a next time! The next time we make plans to meet up, I'm telling her I won't meet with her unless she promises not to lean on my car, but what car you say to these kinds of stubborn people?
