The Pot of Happiness

I want to go shopping.
Come with me, it would be fun.
I promise.
I want to buy a pot of happiness.
With fluffy clouds around the edges,
Some dried flowers and abandoned shells.
Yes, and a handful of twinkling stars.
Oh! And some colorful butterflies fluttering their wings.
But, what it would have for sure, is a key,
That unlocks the secrets of your errant heart.
