I'm tired, boss. Tired of bein' on the road, lonely as a sparrow in the rain. I'm tired of never having me a buddy to be with, to tell me where we's going to or coming from, or why. Mostly, I'm tired of people being ugly to each other. I'm tired of all the pain I feel and hear in the world every day. There's too much of it. It's like pieces of glass in my head all the time. Can you understand?
