Sweetheart of mine, I've 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, it's my heart
