Spring.
While on one of my 'photography walks' in a nearby Oakland neighborhood. There, stabbed into a tree, was a pair of pink scissors. As I calmly adjusted the camera settings to capture this out-of-place implement, a squirrel came and tried to lift these scissors from the tree. A perfect moment. Now, more rapidly adjusting the settings of the camera and lifting to take aim, the squirrel, just as quickly, gave up on his fight to free the scissors and fled back empty handed... and so did I.
Some lessons can only be taught by a squirrel with pink scissors.
I have never missed 'this' shot since.
