Be Careful, It's My Heart

<lengthy instrumental intro>

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 burned
It's not the book i lent you that you'll 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
