I started my car this morning in the dark. It was before 0630, and the sun wasn't up. I started the car and heard voices. I turned up my radio to hear what they were saying, but realized it was set to "AUX" meaning my iPhone. It was in my pocket. Not plugged in. I turned it off, just to make sure. Nope, the voices were still talking. I panicked a bit, my HR spiked and my imagination went into hyperdrive.
Then I realized that the kids' DVD was turned on and it was Flynn Ryder and Rapunzel having a conversation. Then I was ok. But I really panicked before I knew.
