““As you approach Carol, she stands with her back to you, engaged in a conversation. Eager to make a joke about the questionable headwear in the crowd, you tap her on the shoulder. A complete stranger turns to you, confused and slightly irritated. You respond with embarrassment, "I'm sorry, I thought you were someone else." But that's not true. You didn't think she was someone else. You knew she was someone else. You knew she was Carol. You never questioned it. Indeed, you never even thought about it. In the world you experienced, you tapped Carol on the shoulder. She was there, in your brain, not your eyes.””
