The magical word- 'blah'!

I dont care, blah!
That sucks, blah!
Whatever, blah!
This, that, blah blah..
Blah!
A magical word that says so much without saying a word
A mysterious word that hides what it means
A funny word that skirts over the sting
A sarcastic word that reveals the apathy
A sinister word that illuminates the cheerful
A sordid word that communicates the gist
A heavy word to make the conversation light
A cruel word to display diplomacy
A tired word to speak the forgotten
A clever word that highlights the dumb
A sunny word that can brew a storm

A word is never just a word.
