Famous quotes containing the words distance and/or visibility:
“Letters to absence can a voice impart,
And lend a tongue when distance gags the heart.”
—Horace Walpole (1717–1797)
“My children have taught me things. Things I thought I knew. The most profound wisdom they have given me is a respect for human vulnerability. I have known that people are resilient, but I didn’t appreciate how fragile they are. Until children learn to hide their feelings, you read them in their faces, gestures, and postures. The sheer visibility of shyness, pain, and rejection let me recognize and remember them.”
—Shirley Nelson Garner (20th century)
