I can't tell you where a poem comes from, what it is, or what it is for: nor can any other man. The reason I can't tell you is that the purpose of a poem is to go past telling, to be recognised by burning.
“I love driving cars, looking at them, cleaning and washing and shining them. I clean 'em inside and outside. I'm very touchy about cars. I don't want anybody leaning on them or closing the door too hard, know what I mean?”
