Lyrics:
Grass was always greener
Thought she was a keeper
Told me pretty lies
Can't believe that I believed her
Met her in a bathroom
Knew that she was bad news
Now she's running back to
The next best thing
Tell me I'm greening, not even breathing
She wants the next best thing
Head in the ceiling, thinking of leaving
