    "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.
