Famous quotes containing the word families:
“Families have always been in flux and often in crisis; they have never lived up to nostalgic notions about “the way things used to be.” But that doesn’t mean the malaise and anxiety people feel about modern families are delusions, that everything would be fine if we would only realize that the past was not all it’s cracked up to be. . . . Even if things were not always right in families of the past, it seems clear that some things have newly gone wrong.”
—Stephanie Coontz (20th century)
