I help out in a kindergarten class once a week. Many of the kids start the school year not knowing the simplest things, like how to write their names, but they pick it up lightning-fast. They might not know anything about colors or patterns, but the second we show them – almost before we get done showing them the very first time – they understand. I’m thinking in particular of this one bright, beautiful little girl whose eyes light up with excitement as she gets things. She’s so freaking smart and she loves to learn. So here’s my question: how is it possible that this person has been alive for five years, and no one has shown her what BLUE is?
