Law of conservation of happiness

Oh yes... I am convinced that there is definitely such a law. It goes something like this...
"Happiness can only change from one form into another, but the total happiness in the universe will always remain constant."

The proof:
The rain gods finally smiled on us Lukhnowites, resulting in the mercury dipping considerably. There were smiles all around the campus, as the heat had become unbearable earlier. But then, just to prove the "law of conservation of happiness" theory, out came the insects in huge numbers. These ugly and blind creatures are constantly flying in my face. One infernal insect even jumped me in the loo, nearly causing me to pull a vital muscle!! Grrrrr!!
RIght away, they have neutralized my happiness at the advent of the monsoons, and I have returned to my miserable self. Now I cant even enjoy the cold breeze flowing, because if I open the windows those infernal creatures will come in! Quite a catch 22 situation!
