      Mary Allen was my best friend-like the sister I never had. We did everything together, piano lessons,

movies, swimming, horse riding. When I was 13, my family moved to another city. Mary and I often wrote

to each other,and sometimes we saw each other-like my wedding and Mary's. Soon we were busy with

children and moving to new homes, and we wrote less often. One day a card that I sent to Mary came back

with the words "Address Unknown". I had no idea how to find Mary.

     Over the years,I thought of Mary often. I wanted to share stories of my children and then grandchildren.

And I needed to share my sorrow when my brother and then mother died.There was an empty place in my

heart that only a friend like Mary could fill.

     One day I was reading the newspaper when I noticed a photo of a young woman. She looked like Mary

and her last name was White-Mary's married name."There must be thousands of Whites, "I thought, but I

wrote to her anyway. She called as soon as she got my letter."Mrs. Green!" she said excitedly."Mary Allen

White is my mother. "Minutes later I heard a voice that I recognized at once, even after 40 years. We laughed

and cried. The empty place in my heart is filled and there's one thing that Mary and I know. We won't lose

each other again!
