On the other side of the mirror the sky is made of water and the rivers are made of air. You can walk through the dry sand at the bottom of the East River and look up at the watery sky floating over your head. The towers of the Brooklyn Bridge rise out of the sand like eternity's doorstop; I carved my initials on one of the granite blocks right where it passed below the sand. It made me sad to think of all the tons of stonework down there under the sand, that never get to see the light of day.
I walked across the harbor bottom to the ferry terminal at the Battery and looked up at the ferry boats floating above my head in the sky. Somewhere in the sand under the ferry slip there's a souvenir badge from the Bronx Zoo. I dropped it there when I was about seven years old. In the real world it rusted away to nothing years ago, but on the other side of the mirror it's dry and warm, and just as shiny as the day I dropped it.
I decided to walk out to Brighton Beach. About a million years ago on a winter Sunday afternoon when the sun shone yellow and the wind smelled like Thanksgiving I walked this beach with a brown eyed girl with her hair in a pony tail. Her daughter, age six, was playing with the dogs people brought to run on the beach. We took a stick of driftwood and wrote, "I will love you forever." in the sand and signed our names underneath. She told me that when the tide came in and the waves washed this off the beach they would carry it forever through all the oceans of the world. Well, now it's thirty years later and I wondered if she was right.
Sure enough, there was our love letter, lying on the sand, our names on the bottom. The waves broke over my head, air and water rolling together in some hopelessly upside down surf. Her daughter is older today than we were when we wrote that letter in the sand. I hope her mom is happy, 'cos I am.
