The lesson of a love that should display itself easily in spoken word and open look was one Marilla could never learn. But she had learned to love this slim, gray-eyed girl with an affection all the deeper and stronger from its very undemonstrativeness. Her love made her afraid of being unduly indulgent, indeed. She had an uneasy feeling that it was rather sinful to set one's heart so intensely on any human creature as she had set hers on Anne, and perhaps she performed a sort of unconscious penance for this by being stricter and more critical than if the girl had been less dear to her.
