what's on YOUR car?

We were stopped at the gas station, and I ran inside to pay for our gas after pumping. David was driving, and we were in the Blazer. About the Blazer: about a year ago now (maybe less, seems longer), we noticed the hinges on the driver's side door were about to fail. In fear that we'd get the door open and not be able to close it, we started using the passenger door and scooting across the bench seat. This is a real pain, and new hinges are not expensive, but we haven't found the time to bother with it yet. Fast forward to this summer when David parked in an unexpected place and I didn't look before I backed the Tracker right into the Blazer driver's side door, something that makes me cringe every time I see the car door (because I put a BIG honking dent in the thing, totally my fault, totally embarrassing). Now for closer to 2 years, the driver's side window has not rolled down, and this is unrelated to the other problems with this particular door, but it sure has kept me out of drive-thrus, and for that I'm thankful. It's definitely irritating that the passenger has to get out before the driver gets out, though, and since David was driving, I just hopped out, gassed up, and paid. While I was inside the gas station, Dennis asked David "Daddy, what's on top of the car?". It isn't like David can just pop out the window and look or open the door or even roll down that window to ask me to look. So he said "I don't think there's anything on top of the car" while secretly wondering what I had put up there and forgotten about. There was more to the conversation, which I'll reveal in a minute, but when I got into the car, David said "what's on top of the Blazer?" and I immediately started to climb back out and check. He said "when you got out, Dennis asked me that" and I was opening the door to see what it was when he said "the roof--Dennis said there was a roof on top of the car after I insisted there was nothing up there". Smarty pants. He piped up from the backseat "there's a roof on top of the car--it keeps us safe--and there's a windshield in the front of the car to keep the wind out of our faces" and he went on with a comprehensive list of car parts and uses. He sure did make us think we'd left something up there for a minute!
