When Iwas.in the third grade, we had a hunt at school. We gathered up chalk，pencils，stones, and so on, rapidly filling our checklists. It was a very close race. I was out of breath when I reachedthe clover (三叶草)patch in search of the last, most hard-to-find item: afour-leaf clover.

I was pretty sure that I was going to win. 1 have always been able to find four-leaf clovers. I just see them.

I spent my childhood collecting and pressing four-leaf clovers into books at my mother's house. I started with big cloth- and leather-bound books. When I ran out of romantically bound volumes, I began to put my treasures into anything I could find: fiction paperbacks, cookbooks. The same is true in my house today. Shake a book, and a papery treasure just might fall into your hand.

A few years ago, in Nova Scotia, my husband and I pulled off the road for a picnic. The ground was thick with clover. Some shoots had four, five, even six leaves. I lined them up on the picnic table to admire as my husband, never yet having found one four-leaf clover, looked on with awe. To me, it was simple. The differences in their shapes popped out, breaking the pretty pattern of the conventional clovers with their three perfect leaves.

Two summers back, while waiting for an airport shuttle in Munich, I found a tiny four-leaf clover in a traffic circle and put it into my passport. On the way home, my husband and I were upgraded to business class. Friends attributed our good luck to the clover. I think, it's more likely that we were upgraded because a kind customer service officer took pity on us.

People disagree about whether the luck lies in the finding or in the possession of a clover. Some believe that the luck is lost if the four-leaf clover is even shown to somebody else, while others think the luck doubles if it is given away. I believe that positivity is increased by sharing. I feel lucky to find the clovers so often, but I don't think they influence my life any more than it does to share anything a little special—that momentary closeness between you and a friend or a stranger, as you all lean in to wonder at a rare find.
