Age 16, shortly after I got my drivers license and my first car, a sad old Plymouth Station Wagon with big fins, A real chick magnet. Shortly after that I started to date the girl that would be my steady through the last 3 years of High School. She was also a sophomore and lived 5 doors down from our house. We went our separate ways pretty much after HS when we both went to different colleges.
I forgot to add that she is now married and lives about 1000 miles away, but we reconnected at our 50th HS reunion and have kept in touch via e-mail and occasionally Facebook every few week just to keep up with happenings.
