I think this is an amazing image (from today's Guardian) of a small bird lightly perched on razor wire. I don't see any blood.

My guess is that the very delicacy of the perch is what keeps the bird safe.

There's a worthy ambition: to light so softly on the negative aspects of life and thus be unharmed by their potency.

It is an important lesson and one I need to take to heart after more than a few recent heavy landings.
