One of the greatest lessons of my life came from a dog. It was Christmas Eve, 1989, and it happened as our house was burning to the ground. As we stood in the snow in our jammies, our Newfoundland, Alfie kept running back toward the house to make sure all the children were out and that everyone was safe. (We were, thankfully). That action was the most powerful lesson in pure, selfless, unconditional love that I’d ever witnessed.
