I don't know much about the things that make you who you are

A couple of dozen storiessome snapshots from your childhood

But here in the dark it's clear that we both have our share of scars

Some only scratch the surfacesome have sculpted who we are

(chorus)

I don't know which piece is missing from your heart

I don't know which piece is missing



Running around in circles...running into each other

I didn't mean to let you come too close for comfort



Chorus



Now that the shouting's overtry to accept each other

Faults you'll forgive a friend for are hard to take in your lover

And now that I sung about you and all your insecurities

You can take this song and sing it right back at me



I don't know which piece is missing from your heart

I don't know which piece is missing

I don't know which piece is missing

I don't know...i don't know...i don't know
