Last night Cash was talking and talking and talking - i guess he had a lot to say after camping and getting back to school. He asked me all sorts of questions about hair and how your skin knows how to grow hair and where it is and why it is different colors and why Slider's skin makes her hair white. Then it got interesting...he started asking me about different colors of dogs. And asked how "guard dogs" knew where to walk when they helped people. Then it became obvious that he was talking about "guide dogs". Then he asked if Cooper needed a "guard dog". I said, "Why would Cooper need a guide dog?" Cash said, "Because he is blonde."
So then we talked about the difference between the words "blonde" and "blind".
