Famous quotes containing the word families:
“For those parents from lower-class and minority communities ... [who] have had minimal experience in negotiating dominant, external institutions or have had negative and hostile contact with social service agencies, their initial approaches to the school are often overwhelming and difficult. Not only does the school feel like an alien environment with incomprehensible norms and structures, but the families often do not feel entitled to make demands or force disagreements.”
—Sara Lawrence Lightfoot (20th century)
“Peer pressure is not a monolithic force that presses adolescents into the same mold. . . . Adolescents generally choose friend whose values, attitudes, tastes, and families are similar to their own. In short, good kids rarely go bad because of their friends.”
—Laurence Steinberg (20th century)
“Happy or unhappy, families are all mysterious. We have only to imagine how differently we would be described—and will be, after our deaths—by each of the family members who believe they know us.”
—Gloria Steinem (b. 1934)
