After receiving his son’s
letter, the father immediately
replies by sending a letter
back.

Dear Son,
I kNOw that astroNOmy,
ecoNOmics, and
oceaNOgraphy are eNOugh to
keep even an hoNOr student
busy. Do NOt forget that the
pursuit of kNOwledge is a
NOble task, and you can
never study eNOugh.
Love,
Dad
