Across the room, a half-finished crossword puzzle lay abandoned on the coffee table. He should have finished it, perhaps it would have kept his mind busy. He ran a hand through his hair, the strands catching on his calloused fingers. The words in the letter danced before his eyes, each one a phantom limb of a friendship lost. He hadn't felt this way in a long time.
