The sky is green, and the grass is blue

How much can a heart and a troubled mind take, where is that fine line before it all breaks?
I just can't make it one day without you, unless I pretend that the opposite's true...

Rivers flow backwards
Valleys are high
Mountains are level
Truth is a lie
I'm perfectly fine
And I don't miss you
The sky is green
And the grass is blue

- Dolly Parton
