Single happiness

Sound the horns!! Oh joyous day!!
My life seems just begun
It's out with the old and in with the new
Let's start my time of fun

What's this? I hear you cry
What reason for this bliss
Why the vigorous jig of joy
What grand news did I miss

Oh but pardon me, thou kindest sir 
My scoop you seem to have missed
It's the reason for my idiotic smile 
It's why I dance as though I'm pissed 

A decree absolute is at the very core
Of all that is good and pure
And now I'm ready to face the world
Now that I have my cure
