It was the afternoon of December 24, the day before Christmas, but I had to stay to tidy the office. The only thing that ­_41_ my day was the beautifully decorated Christmas tree in our waiting room and a _42_ sent to me by a fellow I was dating—a dozen long-stemmed red roses.

Suddenly, our receptionist came and said there was a lady outside that urgently needed to speak with me. As I stepped out, I noticed a young _43_ woman with a baby in her arms standing there. 44_ , she explained that her husband—a prisoner in a nearby prison—was my next patient. She told me she wasn’t allowed to visit her husband in prison and _45_ he had never seen his son. So she _46_ me to let her wait here ahead of time. I agreed. After all , it was Christmas Eve.

A short time later, her husband arrived—with chains on his feet, cuffs on his hands, and two armed guards _47_ him. The woman’s tired face _48_ when her husband took a seat beside her. I watched them laugh, cry, and share their _49_ . He seemed like a gentle and honest man.

At the end of the _50_ , the man had to go back and I wished him a Merry Christmas. He smiled and thanked me and said he felt saddened by the fact that he hadn’t been able to get his wife _51_ for Christmas. On hearing this, I was _52_ with a wonderful idea.

I’ll never forget the _53_ on both their faces as the prisoner gave his wife the beautiful, long-stemmed red roses. I’m not sure who _54_ the most joy—the husband in giving, the wife in receiving, or myself in having the opportunity to share in this _55_ moment.
