Read the excerpt from "The Story of the Old Man Who Made Withered Trees to Flower" by Yei Theodora Ozaki. Which sentence reveals the theme of companionship? The happiest hour of the day both for the old man and his dog was when the man returned from his work in the field, and having finished his frugal supper of rice and vegetables, would take what he had saved from the meal out to the little veranda that ran round the cottage. Sure enough, Shiro was waiting for his master and the evening tid-bit. Then the old man said “Chin, chin!” and Shiro sat up and begged, and his master gave him the food. Next door to this good old couple there lived another old man and his wife who were both wicked and cruel, and who hated their good neighbors and the dog Shiro with all their might. Whenever Shiro happened to look into their kitchen they at once kicked him or threw something at him, sometimes even wounding him. One day Shiro was heard barking for a long time in the field at the back of his master’s house. The old man, thinking that perhaps some birds were attacking the corn, hurried out to see what was the matter. As soon as Shiro saw his master he ran to meet him, wagging his tail, and, seizing the end of his kimono, dragged him under a large yenoki tree. Here he began to dig very industriously with his paws, yelping with joy all the time. The old man, unable to understand what it all meant, stood looking on in bewilderment. But Shiro went on barking and digging with all his might.
