Famous quotes containing the words features and/or trauma:
“The features of our face are hardly more than gestures which force of habit made permanent. Nature, like the destruction of Pompeii, like the metamorphosis of a nymph into a tree, has arrested us in an accustomed movement.”
—Marcel Proust (1871–1922)
“Living by basic good-mothering guidelines enables a mom to blend the responsibilities of parenthood with its joys; to know when to stand her ground and when to be flexible; and to absorb the lessons of the parenting gurus while also trusting her inner voice when it reasons that another cookie isn’t worth fighting over, or that her child won’t suffer irreparable trauma if, once in a while, Mom puts her own needs first.”
—Sue Woodman (20th century)
