This is what I want in life.
This is a much better rationale/explanation of polyamory than the "many favorite foods" or "more than one child" analogies. The reason, I think, is because it describes a comprehensive and inclusive growth process instead of simply saying you love people or things "equally but differently". I never quite bought into the whole "equal but different" line.
