When I was a child, my grandmother's four dogs and my younger sister inhabited my make-believe world of adventures. My grandmother's enormous house in the mountains of Argentina was backdrop for the plays I starred in. Sometimes I'd let my sister have a part, as long as it was a supporting role. We rode bamboo steeds through the pepper trees, chasing bandits, stopping often for black figs or a fistful of grapes, and continued on. It didn't take much to invent a story and act it out. It was especially dramatic when the thunderstorms came and rumbled through the house, or when flashes of lightning lit up the sky and killed trees. That's when I'd let my sister have top billing and the dogs and I hid backstage in the closet.
