Heart of mine, be still   You can play with fire but you'll get the bill      Don't let her know   Don't let her know that you love her   Don't be a fool, don't be blind   Heart of mine      Heart of mine, go back home   You got no reason to wander, no reason to roam      Don't let her see   Don't let her see that you need her   Don't put yourself over the line   Heart of mine      Heart of mine, go back where you been   It'll only be trouble for you if you let her in      Don't let her hear   Don't let her hear where you're going   Don't untie the ties that bind   Heart of mine      Heart of mine so malicious and so full of guile   Give you an inch and you'll take a mile      Don't let yourself fall   Don't let yourself stumble   If you can't do the time, don't do the crime   Heart of mine
