"Your skins are different colors"

As I'm out on the field coaching during the soccer game I'm visiting with our goaly "B" and Pate. Pate says something to me and calls me mom. "B" says are you her mom? I said yes. He gets the most perplexed look on his face and says "your skins are different colors". I said yes, Pate is adopted. He again gets this really confused look on his face and says "hmmm, ok". It made me smile. I love the innocence of kids.
