Famous quotes containing the word early:
“If you are willing to inconvenience yourself in the name of discipline, the battle is half over. Leave Grandmas early if the children are acting impossible. Depart the ballpark in the sixth inning if youve warned the kids and their behavior is still poor. If we do something like this once, our kids will remember it for a long time.”
—Fred G. Gosman (20th century)
