Reuben decided to raise the five dollars. Hearing the sound of hammering from a side street, he suddenly had an idea. People built their own homes in Bay Roberts, using nails purchased in sacks from a local factory. The sacks were sometimes discarded and Reuben knew he could sell them back to the factory for five cents a piece. Every day after school, Reuben went around the town, collecting nail sacks. When the school closed for the summer, Reuben wandered around the town, searching for his treasures. Often he was tired and hungry, but the thought of the object in the shop window kept him going. Sometimes his mother Dora would ask:“Reuben, where were you？ We were waiting for you to have dinner.”

“Playing, Mum. Sorry.”

Dora would look at his face and shake her head. Boys.

One day in spring, he counted the coins and found that he needed 20 cents more.Could there be any sacks left anywhere in town？ He had to find four and sell them before the day ended.

When Reuben arrived at the factory in the late afternoon, the sack buyer was about to lock up.“Mister! Please don’t close up yet.”The man turned and saw Reuben, dirty and sweat stained.

With four more coins in his pocket, Reuben headed for the shop and got what he wanted. Racing home, he burst through the front door.“Here, Mum! Here!”He exclaimed as he ran to her side. He placed a small box in her work roughened hand.

Dora unwrapped it carefully, to save the paper. A blue velvet jewel box appeared. She lifted the lid and saw an almond shaped brooch (胸针) with the word“Mother.” It was Mothers Day, 1946. Dora had no jewels except her wedding ring. Speechless, she smiled radiantly and gathered her son into her arms.
