Famous quotes containing the word friend:
“A child... who has learned from fairy stories to believe that what at first seemed a repulsive, threatening figure can magically change into a most helpful friend is ready to believe that a strange child whom he meets and fears may also be changed from a menace into a desirable companion.”
—Bruno Bettelheim (20th century)
