I'm Lying lyrics

You taught me all I know You opened up my eyes But now that I have grown You leave me no surprise I tell you I still care I say I want much more But I just grin and bear Until you're out the door Refrain I am lying It's a game I'm learning to play I am lying I'm too cruel to give it away Illusions are my crime They keep me insincere For now, i'll bide my time It's gonna end in tears Refrain How long can I pretend ? How long before I break ? Don't want a bitter end Is this a big mistake ? Refrain I am lying... I am lying...
