Famous quotes containing the word period:
“Not only do our wives need support, but our children need our deep involvement in their lives. If this period [the early years] of primitive needs and primitive caretaking passes without us, it is lost forever. We can be involved in other ways, but never again on this profoundly intimate level.”
—Augustus Y. Napier (20th century)
