Christmas Lost and Found
Christmas was a quiet affair when I was growing up. There were just my parents and me. I vowed that someday I’d marry and have six children, and at Christmas my house would vibrate with energy and life and love.
I found the man who shared my
dream, but we had not reckoned on the possibility of infertility. Undaunted, we applied for adoption and, within a year, he arrived.
We called him our Christmas Boy because he came to us during that season of joy, When he was just six days old. Then nature surprised us again. In rapid succession we added two biological children to the family—not as many as we had hoped for, but compared with my quiet childhood, three made an entirely satisfactory crowd.
As our Christmas Boy grew, he made it clear that only he had the expertise to select and decorate the Christmas tree each year. He rushed the season, starting his gift list before we’d even finished the Thanksgiving turkey. He pressed us into singing carols, our froglike voices contrasting with his
musical gift of perfect pitch. Each holiday he stirred us up, leading us
through a round of merry chaos.
Our friends were right about adopted children not being the same. Through his own unique heredity, his irrepressible good cheer, his bossy wit, our Christmas Boy made our life colorful. He made us look and behave better than we were.
th
Then, on his 26 Christmas, he left us as unexpectedly as he had come. He was killed in a car accident on an icy Denver street, on his way home to his young wife and infant daughter. But first he had stopped by the family home to decorate our tree, a ritual he had never abandoned.
Grief-stricken, his father and I sold our home, where memories clung to every room. We moved to California, leaving behind our friends and church.
