left to build something great (concurrent)

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. I have stood still and stopped the sound of feet when far away an interrupted cry came over houses from another street. But not to call me back or say good-bye; and further still at an unearthly height, one luminary clock against the sky proclaimed the time was neither wrong nor right. I have been one acquainted with the night.
