" Lying awake in the dark that night,unable to sleep, he thought he would have given anything to feel the heavy thud on the bed that used to announce the old dog's arrival. How extremely unloving and intolerant he had felt so often , waking in the middle of the night to the relentless shoving and pushing of his undesirable and selfish bedfellow. "
