Famous quotes containing the words direct and/or secondary:
“However strongly they resist it, our kids have to learn that as adults we need the companionship and love of other adults. The more direct we are about our needs, the easier it may be for our children to accept those needs. Their jealousy may come from a fear that if we adults love each other we might not have any left for them. We have to let them know that it’s a different kind of love.”
—Ruth Davidson Bell. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 3 (1978)
“Words are always getting conventionalized to some secondary meaning. It is one of the works of poetry to take the truants in custody and bring them back to their right senses.”
—William Butler Yeats (1865–1939)
