    I was 15. She looked like she was over 70. But on that day, I think she understood me more than anyone

else.

     Walking into the church that Sunday was hard. I had never let anyone see me cry. But I knew I would

cry that day. My grandfather was suddenly ill. The doctors said he might not live much longer. Everyone in

my family was crying. Grandpa was the sweetest man in the world. Why was he leaving us? 

    There weren't many people at church that day. One of them was an old lady sitting at the end of my row.

She was smiling. I closed my eyes and prayed (祈祷) for my grandfather to get better. Soon, my eyes were

full of tears. I opened my eyes and saw a hand in front of me. It was giving me a tissue (纸巾). 

    The old lady was sitting next to me, smiling. She didn't say a word. She just gave me a tissue and a smile.

I tried to thank her, but only tears came out. Then she took my hand. I looked into her eyes. They were clear

and blue, and they made me feel peaceful. Her smile said to me: I am with you. Everything will be OK. I

closed my eyes again.When I opened them, she wasn't there. I left the church but still couldn't find her. I

never saw her again.

     My grandfather died the next week. We all cried a lot. But when I thought of that old lady's warm smile,

I felt a litter better.
