The Wraith have a very pessimistic view of life. John believes there is always a chance, no matter how slim it is, that things will turn out well. Back home, people change, and evolve, they accept people who are different to them. It wasn't that long ago that a black person and a white person could sit side by side on a bus.

Okay that was weird mental image - Wraith on buses.

John casually shifts his hand to next clump of hair, it's kinda relaxing, this easy closeness and nakedness. "It could further acceptance in a few centuries," he said quite cheerfully. "But don't worry, I am not in a hurry to stand on some podium and announce us. I really am a private guy. I don't want people trying to understand how this works, especially when it's going to take us awhile to work that out for ourselves."
