They make out frantically, in the back of the taxi, her head on his lap bent back. The abandon does not startle their driver, who weaves through Shanghai’s traffic without pause. The man, baseball hat on, looks up briefly as I slip past on my scooter. The woman, face hidden in the dark of seven pm, does not move; her head is back, mouth up in an imagined gasp for air. He, window again free of my shadow, dives down to her waiting lips in my rear view. Where are they going, this couple so enraptured on Tuesday? Where have they been?

Shanghai, like any where, shifts with the lives its people. Like any people, we shift when caught up in each other. A cold ride home through quickly darkening streets becomes a soft journey barely remembered when not alone. It becomes a passel of stories swapped over the wind and horns, becomes the wait for an end that is glorious in anticipation. Likewise, old haunts long since grown repetitious suddenly provide new afternoons of shared wandering.

A conference center never finished stands several blocks south of Zhaojiabang. First discovered in two thousand three while wandering on lunch breaks from an elementary school nearby it is a mystery of Shanghai, of the Asian Financial Crisis, of some bankruptcy somewhere. Its brick and concrete structure sits astride the terminus of Feng Lin Lu and imparts a strange majesty to this neighborhood, still trapped in the repetitive architecture of China’s ’70s and ’80s, rows of short squat flats all the same. The marbled-bodied friezes on the front, strangely fixed in place before the windows, floors, and walls, which were never completed, stare out at the tree-lined avenue. A massive gate, likewise roofed in granite long before the arch was framed completely, has been walled off with blue corrugated metal opened only occasionally by the old man who lives in this complex now alone. There is no mention of the plan, intentions, builder, or the once-imagined grandeur save for a model, tucked away in a section of the surrounding construction wall, it’s glass window originally set up to inspire passers-by and now covered by sheet metal. Sneaking through the old man’s room it becomes visible from an end, an odd angle above and behind the complex. In it the ring buildings are five stories high and roofed with peaks rather than the flat structures of skeletal concrete they remain. The central hotel towers fifteen floors above the surrounding streets, it’s intricate curved entrance wide enough to drive up, it’s elevators’ glassy fronts ascending the building’s outer face, gradually rising out of the courtyard to give a view of Xuhui, of Shanghai.

This building, discovered years ago, is wrecked in the fall of two thousand seven, and only the desire to show another, to be somewhere together, to share this city, brings me back to see it crumble. Four years on the view through fresh eyes returns the joy of discovery to mine. It is two years since I climbed through the complex one Sunday in January with a friend, discussing girls and the chances of surviving them while transposing lives (his) to America. The circle is not lost on me, watching the wrecking crew pillage this gigantic complex, imagining so many parts of the life I have built here come crumbling down in that shudder, this shake. Construction in Shanghai is immediate, constant, and temporary. As if in proof of time’s passing buildings are removed from my life, buildings that contained my history here. The noodle shop of Friday lunches in two thousand three has been boarded up for years, the Out of Africa poster that hung behind the tv leans up against the half-obscured window, a small reminder to old customers. The dates I went there on are likewise lost, only peeking in to my memory occasionally as I pass in the dusk of evening, coming home from Cotton’s, from work, from intoxicating conversation.

In Hongqiao, in two thousand four, there was a noodle shop with a wooden door, carved, eight feet high and four across, of a weight made light by hinges yet massive to the touch. Often, in the cold of February, a boy and girl would sit ensconced behind it, neither entirely familiar with the menu, with the street, with each other, or with the city. They slept in an apartment furnished yet made bare by the cold and their caution, on a street whose name neither would remember. Still strung with Christmas lights Hongqiao’s streets felt empty even when packed with the rush of office workers heading home.

Writing a letter in a cafe near there in the fall of oh seven, the streets of Hongqiao have lost their mystery, and I have joined the work day lunch break.  I can no longer find that door. Has New York shifted this much in four years? Is it Shanghai that changes, or the people, or are they both the same?

I scooter up and down Fuxing, sometimes alone, sometimes not, learning new places, noticing new houses, which are often old houses suddenly discovered behind walls and trees long sheltered. Shanghai changes, as does my focus, and both of us are better for it.

On the first Sunday in December the view in all directions fades into white as the pollution descends low and encapsulates everything, like snow, cutting off sound. On Fuxing, kept warm by arms wrapped around me and slipping through the dust into invisibility, the reason I am leaving - this strangling air - strikes us both as gorgeous, and Shanghai is again a city of picturesque memory.
