Many years ago, when I was a young boy, I remember having a lot of fun visiting my cousin Mary, who was two years younger than I. She lived with her mother and dad on a small ranch.
The best thing about Mary was that she was a tomboy and loved to climb trees, slide down the embankment and jump in the creek. This last activity was especially fun for me, because Mary and I would strip down to our underwear before getting into the water. When we got out of the water in our underwear, we presented a rather revealing picture to each other.
