What's a thematic statement for the following quote from Old Man and the Sea:
When the boy came
back the old man was asleep in the chair and the sun was down. The boy took the old army blanket off the bed and spread it over the back of the chair and over the old man's shoulders. They were strange shoulders, still powerful although very old, and the neck was still strong too and the creases did not show so much when the old man was asleep and his head fallen forward. His shirt had been patched so many times that it was like the sail and the patches were faded to many different shades by the sun. The  old man's head was very old though and with his eyes closed there was no life in his face. The newspaper lay across his knees and the weight of his arm held it there in the evening breeze. He was barefooted.
