Try this for me, sitting at your computer. I want you to imagine the following story. It begins in a misty, featureless plain. It'll only work if you can put yourself there, take a moment if you have to. You're standing in a misty, featureless plain. You feel like you're dreaming, with no sense of time or place. You just are - you, the mist, and nothing. Some distance ahead, a shape can be seen. It's a person, emerging out of the fog. Step by step, they approach. They're standing right in front of you. You look them up and down - they look you in the eye, and say "So... " Cool, thanks. No, that's not it. I want to know what the person looked like! What did your mind conjure? Tall? Short? Fat? Thin? Clothes? Race? Gender? And what did their voice sound like? No points being made here, just pure curiosity.
