Famous quotes containing the word families:
“There is a city myth that country life was isolated and lonely; the truth is that farmers and their families then had a richer social life than they have now. They enjoyed a society organic, satisfying and whole, not mixed and thinned with the life of town, city and nation as it now is.”
—Rose Wilder Lane (1886–1965)
