Owing to my schedule, I spend more time at home with Zeus the dog than my wife does. Even when we're all together, I devote more time to playing and interacting with him. Despite my efforts and my great love for him, I'll never be first in his heart. He will always, always love L the best. When she leaves for work, he goes through a little period of mourning before rejoining me for the day.
I suppose I could be bitter and resentful at being relegated to also-ran status in the mind of the goofy little dog. But I still enjoy our time together. Once he forgets my wife exists, he's perfectly happy to pass the day with me.
Love is a strange instrument. Love really can't make the world do anything it wasn't already willing to do. It can't bring back the people we've lost; it can't even keep someone's affections when they wander elsewhere. Love is the weak force of our emotional universe. It's kind of useless. But we idealize it above all other feelings, and it exerts an alarming authority over us. I love Zeus no matter what he thinks of me.
