She was 6 years old when I first met her on the beach near where I live. She insisted on talking to me. "I'm building," she said. "I see that. What is it?" I asked, not caring. "Oh, I don't know, I just like the feel of sand." That sounds good, I thought, and slipped off my shoes. A sandpiper   glided by. "My mom says sandpipers come to bring us joy." "Good-bye joy," I muttered   to myself, "Hello pain," and turned to walk on. I was depressed; my life seemed completely out of balance. "What's your name?" She wouldn't give up. "Robert," I answered. "Mine's Wendy... I'm 6. Why are you so quiet?" I turned to her and shouted: "Because my mother died!" "Oh," she said quietly, "then this is a bad day." "Yes," I said, "and yesterday and the day before and - oh, go away!" "Did it hurt?" she asked. "Did what hurt?" I was annoyed with her, with myself. "When she died?" "Of course it hurt!" I replied angrily, misunderstanding. A month after that, when I next went to the beach, she wasn't there. Feeling guilty, ashamed, I went up to the cottage and knocked at the door. A young woman answered. "Hello," I said. "I'm Robert Peterson. I missed your little girl today and wondered where she was." "Wendy died last week, Mr. Peterson. She had leukemia . Maybe she didn't tell you." I had to catch my breath, saying nothing. "She seemed so much better here and had a lot of what she called happy days. But the last few weeks, she declined rapidly... "She left something for you... if only I could find it," she said. "Could you wait a moment while I look?" It was a drawing in bright color1s- a yellow beach, a blue sea, and a brown bird.

But then we looked at the picture of the sandpiper and slowly both of us began to smile, remembering the lesson that Wendy had left us.
