Famous quotes containing the word average:
“The average parent may, for example, plant an artist or fertilize a ballet dancer and end up with a certified public accountant. We cannot train children along chicken wire to make them grow in the right direction. Tying them to stakes is frowned upon, even in Massachusetts.”
—Ellen Goodman (b. 1941)
