When a daughter loses a mother, the intervals between grief responses lengthen over time, but her longing never disappears. It always hovers at the edge of her awareness, ready to surface at any time, in any place, in the least expected ways. This isn't pathological. It's normal. It's why you find yourself, at twenty-four, or thirty-five or forty-three, unwrapping a present or walking down an aisle or crossing a busy street, doubled over and missing your mother.
