So, so you think you can tell heaven from hell, blue skys from pain. Can you tell a green field from a cold steel rail? A smile from a veil? Do you think you can tell?

But all individuals are different. Some of us just wouldn't be satisfied with just carrying out a routine job and being happy. Yet I envied those people. I had a brother who I really envied because he was a mailman. But he's the one that had all the fun. He had himself a trailer, and he used to go out and go fishing, and he didn't worry about payrolls and stories and picture grosses or anything.
Sometimes, if you stand on the bottom rail of a bridge and lean over to watch the river slipping slowly away beneath you, you will suddenly know everything there is to be known.
