Every person sees the world through lenses of his or her own design - individual goggles that alter focus and perspective as desired. For those who wish the world to be dark and ugly and unapproachable, it is. But for those who wish it to be beautiful, it is a garden playground blooming with bright, happy colors.
Why did the world go on being so beautiful in spite of the ugliness he had experienced? The lake was beautiful, serenely beautiful. The forest was beautiful, greenly beautiful. Lake and forest, the whole shimmering world was painfully beautiful. He loved this world, but he was too hurt to enjoy it.
