Bathing rights

There is a walk I like to take, past a natural birdbath hewn in a stone face,

where querulous Musk Lorikeets and Rainbow Lorikeets argue over bathing rights.

It makes me think of my son’s Economics notes:

“Economics is the study of scarcity. …

Resources are not few, but relative to wants they are scarce.”

If there is enough for everyone, why do we still argue?
