Jack had to learn to survive on his own because his master, Caleb, was too poor to feed him, despite loving him deeply. _Highlights the theme of poverty and the limits of love in material terms._ > Caleb lifted up his voice and cursed the day wherein he had lost his eyesight. 'If I had but the glimmer of daylight wherewith to guide my steps, I would search the world through' Caleb bitterly regretted his blindness, wishing he could see to search for his daughter's husband. _Shows Caleb's frustration and helplessness._ > All gone but Jack! Well, a dog is something, after all, to have left one; and when one is old and blind and poor, one doesn't expect a great deal in life... After losing his family, Caleb finds comfort in having Jack, and he has learned to be grateful for small mercies. _Reflects the theme of resilience and the value of companionship._ ## Links - HTML: https://www.betterreads.online/discover/short_fiction_61_se/chapters/jack - Book: https://www.betterreads.online/discover/short_fiction_61_se - All chapters: https://www.betterreads.online/discover/short_fiction_61_se/chapters
