Fallingwater and a Seven Year old

My aunt sent me a card with the above picture of Frank Lloyd Wright's Fallingwater. My seven year old son came home, noticed the card on the table and proclaims "I love Fallingwater. I think this is his best work." I asked him who the architect was. He rolls his eyes and says (with "Duh" in his voice) "Frank Lloyd Wright...remember he was from Wisconsin." He continues with "I really want Santa to bring me the Lego Fallingwater." He's SEVEN! God love him, he totally cracks me up. Can you imagine what he is going to be like when he is older?!
