Grenade - Bruno Mars

easy come, easy go that's just how you live oh take, take, take it all but you never give 
should have known you was trouble from the first kiss had your eyes wide open why were they open? 
gave you all i had and you tossed it in the trash, you tossed it in the trash you did to give me all your love is all i ever asked 'cause what you don't understand is 
i'd catch a grenade for ya (yeah, yeah)
