Blue and yellow both want to meet
Without ever turning green.
Each expects the other to defy nature's law.
Yellow wants more yellow,
Blue wants more blue.
When green is inevitably produced,
Both are disappointed.
Everyone wants someone to complete them,
Almost no one wants to complete someone else.
But nature's law cannot be broken:
You cannot take without giving.
The only way yellow and blue can complete each other
Is by embracing the green.
