John and his girlfriend Mary decided to become bank robbers.

Mary did the actual robbing at gunpoint inside the banks, while John waited outside as the getaway driver.

They were successful at first, pulling off a string of heists that made headlines and turned them into folk heroes.

Eventually, their luck ran out and they were caught.

At trial, the judge sentenced Mary to ten years in prison, while John received only two years.

However, once they arrived at their respective prisons, they discovered a clerical error.

John would be serving ten years, and Mary only two.

Mary insisted they report the mistake, but John convinced her to stay quiet.

After two years, Mary was released. She faithfully visited John every month and stayed in touch with letters and phone calls for the remaining years of his sentence.

When John was finally released, they were reunited, got married, moved to another state, and left their criminal past behind.

They raised children, then grandchildren, and lived a long, happy life together.

On their 50th wedding anniversary, family and friends gathered to celebrate.

During the party, someone asked Mary what the secret to a happy marriage was, and why she stayed with John during all those years in prison.

Mary smiled and replied, “Well… you know you’ve found the one when you finish each other’s sentences.”
