You were the huge shape about 5 feet from me, moving so calmly through the water that I first thought you were a shark about to put me on the menu. Fortunately, you were just a harbor seal about to put on an after-dark fish-killing clinic. As my brother and I watched in amazement, you used our lights to catch fish after fish, brushing up against us gently sometimes. Welcome to Mr. Seal's house of sushi. This went on for at least half an hour. I have always told people to not feed the seals or pet them. Well, I might as well be a full-blown hypocrite: I reached out and ran my hand down your smooth, soft skin. You swiftly moved away, intent on filling your belly. Then you were gone—no goodbye, no hug, no kiss and no thank you. My brother and I bobbed on the surface in awe of what had just happened. Incredible, just incredible. May the fur on your fins never be cold. Thanks, Mr. Seal, for the dive of a lifetime.
