Ok I Bought a Car. Now Go Away.

I hate it when I buy a car at a dealership and then like a month later they call me with "special offers" to get me to come in and look at buying another car. Why in the hell would you think that I would need another car after owning my new car for only a month? Do you know something about this car that I don't know? When you sold it did you think to yourself "yeah he'll be back in a month..I better get his number so I can call him with our special offers"? Then, if I have a problem or any questions about the car, the guy who sold it to me is nowhere to be found. He's "on vacation" or "out on the sales floor" constantly. NO I don't want to buy another car a month after owning my new one. Stop being an idiot and leave me alone. Don't call me. I'll call you. Even if you won't be there.
