Virginia Woolf said this quote
“ ...children never forget. For this reason, it was so important what one said, and what one did, and it was a relief when they went to bed. For now she need not think about anybody. She could be herself, by herself. And that was what now she often felt the need of-- to think; well, not even to think. To be silent; to be alone. All the being and the doing, expansive, glittering, vocal, evaporated; and one shrunk, with a sense of solemnity, to being oneself, a wedge-shaped core of darkness, something invisible to others. ”
