My 11 year old grandson and I had the following conversation: I asked him about gym class one day, and asked if both both boys and girls were in the same class. He said " yes" and I asked what the kids do in gym nowadays. He said they run laps around the gym and play sports. So I asked him if the girls had "boobies" and he told me, "no" we all wear gym uniforms. My husband and I chuckled, as when we were in school back in the 60's, the boys and girls were separated. So being the great kid that he is, he asked why we were laughing, and we told him we were happy that he was getting some exercise, besides playing "gameboy" and "WII" You have to love their honesty and cherish the days, as they grow up way too quick nowadays.
