Shooting from the hip.

--------
As I waited for the bus home in Manchester city centre - a few minutes after this photo - I saw a young couple leaning against a wall and having a moment.
I instinctively lifted the camera and as I did, their intimate conversation snapped into an argument.
An even better photo opportunity!
For a split second I took stock of where they were, and the building I was facing. A sign above the door said "Pregnancy Advisory Service."

I didn't take the photo.
Some things just aren't fair game when you've got a camera in your hand.
