Be careful, it's my heart.
It's not my watch you're holding,
It's my heart.
It's not the note I sent you
that you quickly burned.
It's not the book I lent you
that you never returned.
Remember, it's my heart.
The heart with which so willingly I'd part.
It's yours to take, to keep or break,
but, please, before you start,
Be careful, it's my heart.
