Catching a glimpse of a fox crossing a road.
Queuing for a McDonald's breakfast behind a fleet of blue toothed up cabbies.
Traffic cones being gathered after night road closures.
Inane or prerecorded radio broadcasts.
Morning papers still strapped in plastic in a pile on the pavement.
Street cleaning machines sweeping up yesterday's detritus in rapidly spinning bristles on spindles.
The chirping of the dawn chorus.
The sun presenting its glorious and powerful rays to a new day filled with hope and potential.
All of these things are signs witnessed at the crack of dawn. An extra few hours of kip and you'd be none the wiser, but the activities would have all taken place.
