You mean HE?

Yesterday after swim lessons Cash was playing on the play ground at the swim place. And I over heard a lady reprimanding him for apparently pushing a littler kid out of the way. I rushed over and said Cash- what did you do, you better apologize but then the lady chimed in and said "she did.... and, she was.... " (I HONESTLY DIDN"T HEAR A THINK SHE SAID AFTER SHE REFERRED TO CASH AS A SHE) and I said "she? She?, you mean HE? She is a He, he's a boy." and she said "Oh - well it was the hair. " Yeah- and I moved onto telling Cash he needed to apologize. I was very abrupt with the lady- but mainly because I was abrupt about my son misbehaving. And then the lady was all nice- how old is He? Oh he looks tall..etc.... being nice. All the while I kept looking at him and what he was wearing and thinking to myself - his clothes read ALL BOY to me. Grey sneakers, Grey - 'where the wild things are'- t-shirt and blue jeans. I just can't see a girl at all. I am so biased I am blinded and cannot see how he looks remotely like a girl. I mean, I know he is adorable and looks so cute and I think he looks like me a bit when I was young- so maybe that is how he looks like a girl. Plus I trimmed his hair a few weeks ago. He is just a surfer boy.
