A Sum of Parts

A part of me remained with you
A bit of me that was free to live
And express my innermost self

A bit which broke apart and left
Never to return, but in my dreams
Ever since you had to leave as well

And a part of you remains with me 
A part you never dared acknowledge
A part you left behind to move ahead

A part of you which did resonate
With me when for moments lost
Between us there was no difference

We are but sum of all of our parts
Small bits collected here and there
To break and form as our life passes
