I have a twin who lies within,
He's always got a happy grin.
He's tall as me but much more thin.

He's got my back, he's staunch and true,
And what I do, he does it too.
My silent partner, out of view.

I know that there will come a day
When we will part, each to his way,
And he'll lie down and there he'll stay.

But till that time I shall not grieve,
I see his smile and apperceive
That he's with me and will not leave.
