Ghost Story

Normally I take our dogs out for a walk at twilight, when the heat of the day makes room for the cool breeze from the Atlantic. Luna's all-white fur shines beautifully in that fading light. When I started taking Luna out for her daily walks, I noticed that the Brazilian kids moved to the other side of the street when they happened to cross our path - something they don't do with our other dogs.
One day, a courageous little kid asked from a safe distance, thus putting an end to the mystery: "Is it a ghost?"
