Famous quotes containing the words family, core and/or differences:
“The family is constantly changing, as each member changes. Some changes we recognize as developments, and the pleasure they bring usually makes us more adaptable. Some changes threaten, or disappoint other members, who may try to resist the change, or punish someone for changing.”
—Terri Apter (20th century)
“Individual science fiction stories may seem as trivial as ever to the blinder critics and philosophers of today—but the core of science fiction, its essence ... has become crucial to our salvation if we are to be saved at all.”
—Isaac Asimov (1920–1992)
“The extent to which a parent is able to see a child’s world through that child’s eyes depends very much on the parent’s ability to appreciate the differences between herself and her child and to respect those differences. Your own children need you to accept them for who they are, not who you would like them to be.”
—Lawrence Balter (20th century)
