to live a simple (简朴) life. Sometimes her children went to see her during their holidays, ubt they stayed with

her for only two or three days.

the fire and gave it some milk and bread. At first the poor dog ate nothing and that afternoon it drank some milk

and three days later it was all right. Now the old woman found it was a beautiful dog. And she liked it very much

and took it everywhere she went. A week later she went shopping with her dog. At a bus stop a young man
