Because of you
歌手：kelly clarkson 专辑：breakaway
I will not make the same mistake that you did. I will not let myself cause my heart so much misery. I will not break the way you did, you fell so hard. I've learned the hard way to never let it get that far.
Because of you
I never stray too far from the sidewalk
Kelly Clarkson
Because of you
I learned to play on the safe side, so I don't get hurt
Because of you I find it hard to trust not only me, but everyone around me, Because of you, I am afraid.
I lose my way and it's not too long before you point it out. I cannot cry because I know that's weakness in your eyes. I'm forced to fake a smile, a laugh, everyday of my life
