Let me die smiling

If my body was on fire, you'd watch me burn down in flames. You said you loved me, you're a liar, 'cause you never, ever, ever did, baby. I'd catch a grenade for you. Throw my hand on a blade for you. I'd jump in front of a train for you. You know I'd do anything for you. I would go through all of this pains, take a bullet straight through my brain. Yes, I would die for you, baby, but you won't do the same.
