I watched a woman trying to quietly take a picture of a swallow on the train station platform this morning. The bird flew away before she'd got her desired shot and she turned to look at me in disappointment.
On the same day, while resting on a bench at the Royal Academy forecourt, I watched a little girl chase after some pigeons. She was carefully measuring her footsteps and pace so they wouldn't fly away. She then took one step too far and they all flew away.
