Nancy Cobb said this quote

My grandmother’s unkindness, for instance, was the result of repressed grief over three deaths: her parents, before she was twelve, and her firstborn child. I don’t recall ever seeing her smile. She was critical of everything and everyone. Table manners, posture, diction, wardrobe. My aunt, her mother’s staunchest defender, often reminded us that my grandmother suffered from accumulated sorrow, bottled up since childhood and cloaked in intellect and intolerance as she grew older. She was never able to grieve fully or mourn the amassed losses, my aunt had said. If we repress our grief, over time, it’s bound to harden the heart.
