Signed, Sealed And Delivered

Signed sealed and delivered a package containing my heart
To open remove the wrapper but please don't tear it apart
You tore out this heart when you left me you left me so sad and so blue
I'm sending this special delivery please handle with care it's for you

It's all that I have to offer but darling you know that it's true
Signed sealed and delivered the postman will bring it to you
I thought perhaps you would keep it just for a while don't you see
Oh darling please keep it forever without you it's no good to me
