Sweetheart of mine I sent you a valentine
Sweetheart of mine it's more than a valentine
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 part
It's yours to take, to keep or break
But please before you start, be careful, be careful
Be careful it's my heart
