"Look at the light, lad. Looks invisible, doesn't it?""Yep.""Put it through a prism, and you get all the colors of the rainbow. Did y'know that a deer can't see the colors we do? He's color-blind, which why hunters can wear bright orange without being spotted. Now, I think we're like the deer in a way. We're blind t'some colors, some spirits, to part of what's real. We're small and ignorant, but we got a whole lot of pride. We're blindest of all when we think we see best."
