Brainy and Proud

I know you are one of a kind,
You have a brilliance that exudes, that's fine.
This and that, here and there,
And yet I have a comment to share.

Intelligence is a gift for men to use,
It is meant to be shared and not abused.
Mind your confidence, you might step on other's toes,
Your wrong grammar is contributing to my woes.

Cause and cost are two different words.
Pronounce it well, don't sound absurd.
You are overbearing, you think you're always right
Your listeners are tired, you come from a dark light.

Believe in what you know,
Share it, make it grow.
Do not lose your sense of hearing, listen.
Because with your face I'm not smitten.
