"Because of our natural aversion to inequality ... we sometimes find generosity as annoying as selfishness."
That about sums it up.
Of course, one study does not constitute final proof.

That is, it's perfectly natural to appreciate help of the kind Daphne and I have sometimes received; and to resent it for the situation it represents.
