It was an autumn morning shortly after my husband and I moved into our first house. Our children were upstairs unpacking,and I was looking out of the window at my father moving around mysteriously on the front lawn. “What are you doing out there?” I called to him.

He looked up, smiling. “I’m making you a surprise.’’ I thought it could be just about anything. When we were kids, he always created something surprising for us. Today, however, Dad would say no more ,and caught up in the business of our new life ,I eventually forgot about his surprise.

Until one gloomy day the next March when I glanced out of the window,I saw a dot of blue across the yard. I headed outside for a closer look. They were crocuses (番红花)throughout the front lawn 一 blue, yellow and my favorite pink ,with little faces moving up and down in the cold wind. I remembered the things Dad secretly planted last autumn. He knew how the darkness and dullness of winter always got me down. What could have been more perfectly timely to my needs?

My father’s crocuses bloomed (开花)each spring for the next five seasons, always bringing the same assurance: Hard times are almost over. Hold on, keep going, and light is coming soon.

Then a spring came with only half the usual blooms and the next spring there were none. I missed the crocuses ,so I would ask Dad to come over and plant new bulbs. But I never did. He died suddenly one October day. My family were in deep sorrow, leaning on our faith.

On a spring afternoon four years later, I was driving back when I felt depressed. It was Dad’s birthday, and I found myself thinking about him. This was not unusual — my family often talked about him, remembering how he lived up to his faith. Suddenly I slowed as I turned into our driveway. I stopped and stared at the lawn. There on the muddy grass with small piles of melting snow ,bravely waving in the wind, was one pink crocus.

How could a flower bloom from a bulb more than 18 years ago, one that hadn’t bloomed in over a decade? But there was the crocus. Tears filled my eyes as I realized its significance.

Hold on, keep going, and light is coming soon. The pink crocus bloomed for only a day, but it built my faith for a lifetime.
