     We always celebrated Dad's birthday on Thanksgiving Day, even after he entered a nursing home. When

we knew it might be his last birthday, the whole family decided to come together for a huge birthday

celebration at the nursing home.

     Dad was a good storyteller. But this time I told Dad that it was now his turn to listen to some stories for

a change. One after another, people told stories from their hearts, while Dad listened with tears in eyes. People

recalled kinds of stories ----stories about when they were little, stories about when Dad was young, and stories

that shared family treasures.

     Everyone seemed to have more than one story. Even the little grandchildren couldn't wait to tell Dad why

they loved him. For a man who had been kind to so many hundreds of people in his life, here was a change

to tell him how much we love him. A few months later, at Dad's memorial service, we more fully realized

what we had given to Dad that night. Those are the stories people normally tell at a funeral (葬礼) after a

loved one is no longer alive to hear the words. They tell stories, full of tears. But we had given those memories

to Dad in his life, and we had told them through laughter, together with hugs and joy. He had them to hold and

enjoyed them from time to time in his mind during his last days and months.

     That's the ways to give back love and that's our chance to celebrate a person in his or her life.
