That's funny... and familiar.... I had a similar incident when I was about 12 or 13. My parents woke up when the back door opened and the screen door closed (which indicated someone going out) and my Dad got up to see what was going on (this was about 5:30 or 6:00 am on a summer day). Looking out the kitchen window he saw me walking towards the neighbor's house, in my skivvies, on a very determined mission. Without a second thought, he came barreling after me to grab me right in the middle of my perceived goal of saving the neighbor lady from Martians! My Mom also got up and made it to the kitchen window in time to see my Dad leading me back home. She said it was quite a sight seeing us returning, BOTH of us in our underwear!!! Good thing it was early in the morning and we lived in the country, so no one observed this strange sight. And yes, I must have been successful, because our neighbor lady did NOT get abducted by aliens! Thanks for the memory!
By the condition of the whitewalls I'd say that although she was a hell of a looker, she was NOT much of a driver!!
