Is he your son

I had to take Christopher into school this morning as we left his book bag as at school yesterday. While we were walking down the hall a cute little black girl starts walking with us. She asks if I am Christopher's daddy. I say yes. The little girl then says but he looks white and you are black. I then ask the little girl if everyone in her family are the same color. She tells me yes. So I try to explain to the little girl that my mom is lighter than me(light skinned black) and my dad is darker than me(dark skinned black). I don't think she understood but it was funny to me.
We had our first parent teacher conference last night. We were a little nervous going into it but it all worked out. The teacher seemed pretty happy with his progress. He is on track to complete all the targets the school has set for kindergartners. It was a little awkward when he drew a picture and wrote that his family likes to play wii.
