Behind the Smile

I haven't been a good friend
 For a long, long time.
 You know I wasn't happy
 Behind the smile.
 Anywhere you look
 A reason to believe.
 But think of what it took
 To bring me to my proper place.
 And I haven't been a good friend
 For a long, long time.
 I haven't been a good friend
 While you've been mine.
 Now am I by side
 Or standing in your way?
 'Cause if this is a sign
 I don't know what it's supposed to mean
 And I haven't been a good friend
 For a long, long time.
 I haven't been a good friend
 While you've been mine.
 ♪
 I have seen my perfect day
 I have watched it fade away.
 You know I'm fighting to believe.
 I haven't been a good friend
 For a long, long time.
 You know I wasn't happy
 Behind the smile.
