Don't laugh, folks, but when I was real, real little, i saw a little boy in my kiddie-camp group with his pants down and noticed his body looked different from mine "down there." Well, I thought HE HAD A DISEASE that made him look that way. I saw my baby cousin being diapered and saw he looked the same as my campmate, and I thought he too had "caught the disease." I learned the truth when I was about 6.
