"It's Christmas Eve"
"I remember one Christmas Eve and he was going to visit his sister in Atlanta. We’re still there. It’s Christmas Eve. He’s still designing, looking at his watch, working until the last moment. That was how much he loved doing what he did. And he did it faster than I’ve ever seen anybody do it. He’d have it already done in his head. Philip Johnson used to say “The speed of his mind…” He’s so underrated that way."
