Mrs. Hunt is sixty years old. She lives in a farmhouse in the country with her dog Bill. Her son Sam is twenty-one years old. At first, he works in a shop in the country and lives with his mother. But now he finds new work in a town and lives there. It’s quite a long way from his mother’s house. She isn’t happy about this. Sam says, “There isn’t any good work for me in the country, mother, and I can get a lot of money in the town and give you some every week.”

One day Mrs. Hunt goes to see her son, and she goes there by train. Sam meets her at the train station. She asks her son, “Why don’t you phone me?”

“But mother, you haven’t a phone.” Sam says.

“No,” she answers, “I haven’t, but you have one!”
