Not As Smart As I Thought I Was, but Not As Dumb As I Could Be

This morning our family was all piled into our van to head out on an outing. For the last year or so our van has had small and sometimes odd things go wrong with it, so much so that we kind of expect weird things to happen. My husband started to get into the van, put the key in the ignition and turned the engine on, then went back in to get something he had forgotten. You know how in newer cars when you leave the door open with the key in it will have that obnoxious ringing sound? Well of course that was the case, only the tone kept getting louder and LOUDER. Great, I thought, the van is doing weird things again. Imagine my consternation when D got in the drivers seat, and closed the door, and the loud tone continued! He turned the engine off, and the tone stopped, of course. But when he turned it on again, the tone was back, even though the door was closed. I was frustrated and said, lets just go! So we started backing out of the driveway, and I reached over to do something with the radio, and WOW! When I turned the volume down, the tone went away. For some reason, whatever radio station it was tuned to, was playing the obnoxious tone, which is miraculously the exact same pitch as the door is open tone. I wonder if scientists had to determine what would be the most grating tone to make people notice things like that. I bet someone got paid to come up with that sound.
I guess I shouldn't feel so dumb...at least we didn't take it to a shop to get it fixed.
