"Hey, I forgot my keys inside. Do you want to drive to the gas station?"
"Okay, but I know you like super-clean cars and my car is filthy so you need to mentally prepare yourself for that before you get in."
"Yeah, that's alright."
...INSIDE THE CAR...
"Geez, this car IS filthy."
"I told you what to expect before you got in."
"I didn't think it would be this bad. Look how thick the dust on the dashboard is."
"You need to assume the worst when I give you a warning like that. HEY! Stop rubbing your fingers around in my dust. You're making it look like crap."
