     "Grandma, Grandma, tell us a story!" Four darling children sat by my feet, looking up at me

expectantly.

     Suddenly, we were interrupted clapping. "Terrific, " the director said, stepping up the stage from the

aisle(过道). "Except, could you kids face the audience a bit more?"

     The kids shifted to face the empty seats, which would be filled in a few days for the church play.

"Perfect, " the director said. "Now, Grandma, read to your grandchildren." A pang of sadness hit me. If

only I could read to my real grandchild!

     I had a granddaughter, but I'd never met her. Sixteen years earlier my son was involved in a relationship that ended badly. But out of it came a blessing: a baby girl named Lena. I hoped to be a grandmother to

her-but shortly after the birth, the mother moved without any address left. Over the years, I asked around

town to try and find my son's exwife(前妻), but it seemed that she didn't want to be found.

     I'd just joined this new church a week earlier, and was at once offered the part of Grandma in the play. At least now I could pretend to be a grandma. The rehearsals went well, and finally the day of the show

arrived. The performance was great. "You all looked so natural up there, " one of my friends said.

     Afterward, we went to the church basement for refreshments(茶点). I walked over to one of the girls in the play, Rehearsals had been such a whirlwind(一片忙乱) that we never really got to talk. "How's my

granddaughter?" I joked.

     "Fine!" she answered. Just then, someone else walked up and asked the girl her name.

     I wasn't sure I heard the girl's answer correctly. But it made me ask her another question. "What's your mother's name?"

     She told me, I was still in shock. "And what's your father's name?" I asked. She told me. It was my

son.

     She'd only started going to that church a week before I did. Since that day of the play, we've stayed

close. Not long ago, she even made me a great grandma.
