Life is made up of moments, small pieces of glittering mica in a long stretch of gray cement. It would be wonderful if they came to us unsummoned, bu… - Anna Quindlen

The lightning bugs are back. They fly low to the ground as the lawn dissolves from green to black in the dusk. Seeing them, I can reconstruct a childhood: a hot night under tall trees; the Good Humor man, in his square white truck, the freezer smoky when he reaches inside for an ice cream.

The lightning bugs trapped in empty jars with holes on top. "Let them out," our mother said, "or they will die in there." We were careless. We always
forgot to open the jars. The bugs would be there in the morning, their yellow tails dim in the white light of the summer sun, pathetic as they lay on
their backs. We were always horrified by what we had done. As night fell we shook them out and caught more.

I relive the magic of the yellow light without the bright white of hindsight. The little flares in the darkness, a distillation of the kind of life we think we had, we wish we had, we want again.

It's funny, isn't it, what will make you break? Your lover moves to London and falls in love with a news reader for the BBC and you feel fine and then one day you raise your umbrella slightly to cross Fifty-seventh Street and stare into the Burberry shop and begin to sob. Or your baby dies at birth and five years later, in an antique store, a small battered silver rattle with teeth marks in one end engraved with the name Emily lies on a square of velvet, and the sobs escape from the genie's bottle somewhere deep in your gut where they've lain low until then. Or the garbage bag breaks.

Every reader, I suspect, has a book like this somewhere in his or her past, a book that seemed to hold within it, at that moment, all the mysteries of the universe.
