An old man lived alone in a village. He wanted to spade his potato garden, but it was very hard work. His only son, who would have helped him, was in prison. The old man wrote a letter to his son and mentioned his situation.

"Dear Son, I am feeling pretty bad because it looks like I won't be able to plant my potato garden this year. I hate to miss doing the garden, because your mother always loved planting time. I'm just getting too old to be digging up a garden plot. If you were here, all my troubles would be over. I know you would dig the plot for me, if you weren't in prison. Love, Dad"
