Baggage now rolls through here on castors, pulled by shuffling feet: the dull drag of rubber and plastic and their many compounds. But occasionally, just occasionally, in a well-heeled step, there is an echo of times when stilettos clicked and nylons swished and when people were taught to pick their leather-shod feet up. And for just a moment here conversations pause, readjust to the acoustic possibilities of the curving space, taking refuge from the whipping wind that scatters voices like leaves.
