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