Elizabeth Gaskell said this quote
“ Another year passed on . The waves of time seemed long since to have swept away all trace of poor Mary Barton. But her husband still thought of her, although with a calm and quiet grief, in the silent watches of the night :And Mary would start from her hard-earned sleep,and think in her half dreamy, half awakened state, she saw her mother stand by her bed-side ,as she used to do 'in the days of long-ago'; with shaded candle and an expression of ineffable tenderness, while she looked on her sleeping child. ”
