A poem begins with a lump in the throat; a homesickness or a love sickness. It is a reaching-out toward expression; an effort to find fulfillment. A complete poem is one where an emotion has found its thought and the thought has found words.
I have been one acquainted with the night. I have walked out in rain - and back in rain. I have outwalked the furthest city light. I have looked down the saddest city lane. I have passed by the watchman on his beat And dropped my eyes, unwilling to explain.
