A dog — a dog teaches us so much about love. Wordless, imperfect love; love that is constant, love that is simple goodness, love that forgives not only bad singing and embarrassments, but misunderstandings and harsh words. Love that sits and stays and stays and stays, until it finally becomes its own forever. Love, stronger than death. A dog is a four-legged reminder that love comes and time passes and then your heart breaks.
