3. The bridge.

There was a bridge in the city, a large one, one of a number spanning out in every direction, and over it there was a constant flow of people going back and forth. A pair of eyes regarded this river of people intersecting the river of water below, not looking at any of the figures themselves but rather the flow of them.

The water below was still enough that the reflection of the bridge could be seen, with its burden of movement. At night, lights would be lit along the bridge, and its twin in the water below would be indistinguishable from it.
