The fact of Barack Obama, of Michelle Obama, changed our lives. Their very existence opened a market. It is important to say this, to say it in this ugly, inelegant way. It is important to remember the inconsequence of one's talent and hard work and the incredible and unmatched sway of luck and fate. I knew it even as it was happening. I felt that I had not changed, but the world was changing around me. It was as if I had spent my years jiggling a key into the wrong lock. The lock was changed. The doors swung open, and we did not know how to act.
