Give and take
Or both. Or neither.
She was a giver.
She cut off her hair
and gave it to the birds.
They made a cozy nest.
She was happy,
until her head got cold.
She cast a meaningful
glance at the birds,
who warbled their gratitude,
but it was not enough.
So she made herself
a feathered hat.
She was a taker.
I think you are saying more than reciprocity....
When we give, we expect adulation, indebtedness. And if we don't get that (to our liking), we stop the charity, to join the herd.
Something like that?
reciprocity is everything
