grenade.

"I'd catch a grenade for you
I'd 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  agree, Bruno Mars knows every promise which a typical girl would want to hear from her lover. I am currently listening to his songs (Just The Way Yuo Are and Grenade) and  I'm addicted. Why did 'he' never tell me these things? Oh! Here we go again! Better stop right here before I mention names. =))
