Avenue Q-There's a fine fine line

Kate Monster:

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.
And I don't have the time to waste on you anymore.
I don't think that you even know what you're looking for.
For my own sanity, I've got to close the door
And walk away...Oh...
There's a fine, fine line between together and not
And there's a fine, fine line between what you wanted and what you got.
You gotta go after the things you want while you're still in your prime...
There's a fine, fine line between love
And a waste of time.

Note:
Bitter but true
What's not kill you
Good for you ( i think )
