While I was driving

While I was driving today, it suddenly started getting really cold in the car. No matter how high we turned the heat, it wouldn't get warmer. We thought that either it was just so cold outside that the heater stood no chance or that the car was breaking. Once we switched drivers though, we figured it all out. I had accidentally tilted open the sunroof. Whoops! Also a possibility that the leash fell out when I was opening and shutting doors to make sure they weren't letting in cold air. I don't think so though, i'm not quite THAT oblivious!
