Sung to a dove through a train window

In the time it took to say this many words out loud,
I'd lost sight of you.
It took its own space up, though, that moment,
You, suspended in air, like any other passenger headed the same way as the train for awhile.
As we outpaced you, I could see how frantic your wingbeats were - -
Rounding the corner, shank to shoulder, I got a chance at such a view –
You were still, more still than the street, still falling behind.
To the street you must have seemed like a stone flung forward
But from where I saw you what stayed me was how hard you were working.
