If I have someone I don't like- an enemy-it always grates on me to find a place where our humanity overlaps. I'm surprised when I bump into them in a restaurant I like, or at the Farmer's Market, or at a concert. These are MY places, My likes, My ideas. "What are you doing here?"
That is the rub. I share a common humanity with my enemies, and often common tastes and even religion.
I'd rather pull our circles completely apart.
