Play with your words

Don't be so serious.

A laugh gets more attention than a whine.

"Man is the only animal that laughs."
  sorry leaving out part of Hazlitt's quote.
     Actually, a huge portion of it.

Used to that these days?

Words I first read when I was eight.

Started thinking about them at ten.

Thought I understood them a few months later.

Changing my mind,
  always while I play with words.
