In the soft gray light filtering through the window, my gaze inevitably lands on the silver photo frame on my bedside table. There, a moment of perfect happiness is frozen in time: my late husband Tom, his arm draped around our only daughter Jessica, and our grandson Ethan, a small boy with an old soul, perched on his grandfather’s knee. They all smile back at me, their joy a silent, daily greeting from a world that no longer exists.
