""There's a fine, fine line between a lover and a friend;
There's a fine, fine line between reality and pretend;
And you never know 'til you reach the top if it was worth the uphill climb.

There's a fine, fine line between love
And a waste of time.

There's a fine, fine line between a fairy tale and a lie;
And there's a fine, fine line between "You're wonderful" and "Goodbye."
I guess if someone doesn't love you back it isn't such a crime,
But there's a fine, fine line between love
And a waste of your time.
"
