The Fray - How To Save A Life
Step one you say we need to talkHe walks you say sit down it’s just a talkHe smiles politely back at youYou stare politely right on throughSome sort of window to your rightAs he goes left and you stay rightBetween the lines of fear and blameAnd you begin to wonder why you came
Where did I go wrong, I lost a friendSomewhere along in the bitternessAnd I would have stayed up with you all nightHad I known how to save a life
Let him know that you know bestCause after all you do know bestTry to slip past his defenseWithout granting innocenceLay down a list of what is wrongThe things you’ve told him all alongAnd pray to God he hears youAnd pray to God he hears you
Where did I go wrong, I lost a friendSomewhere along in the bitternessAnd I would have stayed up with you all nightHad I known how to save a life
As he begins to raise his voiceYou lower yours and grant him one last choiceDrive until you lose the roadOr break with the ones you’ve followedHe will do one of two thingsHe will admit to everythingOr he’ll say he’s just not the sameAnd you’ll begin to wonder why you came
Where did I go wrong, I lost a friendSomewhere along in the bitternessAnd I would have stayed up with you all nightHad I known how to save a life
