A boy is desperate to get money from his father, so he write a letter
to his father..

Dear Dad,

$chool i$ really great. I am making lot$ of friend$ and $tudying hard. With all my $tuff, I $imply can’t think of anything I need, $o if
you like, you can ju$t $end me a card, a$ I would love to hear from you.

Love,Your $on.

A week later….the response from Dad arrived:

Dear Son,

I kNOw that astroNOmy, ecoNOmics and oceaNOgraghy 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.
