Happiness is a hard concept to quantify. All I know is that I can feel my heart swell and my brain relax. I try to savor the moment and give myself over completely to the bliss. The fear of losing the moment almost makes it more special. Everything else becomes less important for a second. Then, one thing changes, the feeling is lost, and only a slight smile is left in its wake.
This feeling is, today and every day, created by a dog draping itself across my lap and falling into a deep sleep.
