Why Effervescence?

I'm sure you've seen a freshly opened bottle of coke. Its so full of these little bubbles.. I've never been sure what do they represent.. is it the happiness of being let out? or is it the anger of a disturbed peace? Whatever it is it sure does display one state of mind quite clearly and that's non passivity. I'm also in that state of the mind right now... I'm not really sure if I'm happy or I'm sad... I'm just aware that I'm not at peace! 

And of course it goes without saying, it is the matter of the heart!!! What else could it be this time of the year?? But this one's a little different... this one is more of battle won yet lost...
