Famous quotes containing the words ground and/or support:
“Our children do not want models of perfection, neither do they want us to be buddies, friends, or confidants who never rise above their own levels of maturity and experience. We need to walk that middle ground between perfection and peerage, between intense meddling and apathy—the middle ground where our values, standards, and expectations can be shared with our children.”
—Neil Kurshan (20th century)
“Many people now believe that if fathers are more involved in raising children than they were, children and sons in particular will learn that men can be warm and supportive of others as well as be high achievers. Thus, fathers’ involvement may be beneficial not because it will help support traditional male roles, but because it will help break them down.”
—Joseph H. Pleck (20th century)
