I've lost a handful of pieces:

As a results of how many times you have -

broken me up

and

tore me apart,

just to piece me back together.

It's like my heart is some sort of special edition Lego you like to lay out on your work desk and assemble just to dissemble.

It leaves me at a tangent.

To the point where I've mastered the art of breaking and bending but not falling apart

You see there's pieces that one can do with out...
