Have you ever noticed the way a cat stares out the window.
Not relaxed, nor pouncing position, but ready.
He sits ready for anything to come through the window. 
If a bird lands, he'll see it. 
If a branch breaks, he'll hear it.
The window is the only thing in sight.
It's his one and only focus. 
Yet, at any given moment,
his lady friend could easily sneak onto him. 
And his focus will stray away from the window, only to focus on her.
And when she leaves,
He'll struggle to stay focused on the same window.
Their purring will echo in his head,
And his focus will forever be distorted by these memories.
