Famous quotes containing the word early:
“Very early in our children’s lives we will be forced to realize that the “perfect” untroubled life we’d like for them is just a fantasy. In daily living, tears and fights and doing things we don’t want to do are all part of our human ways of developing into adults.”
—Fred Rogers (20th century)
