Shows just how little we’ve evolved....
Male cardinals (the bird, not the clerics— as far as I know) do a similar thing. They get food and feed it to the female. I have seen this at my birdfeeders at home. This is part of the courtship ritual. Whether this should be called “payment” or simply showing one’s interest remains to be argued, as to cardinals, monkeys and humans. And if grooming your girlfriend is payment, then I guess opening the door for her, bringing flowers or candy, even telling her how pretty she is are all forms of “payment.” I don’t think my wife is going to be too pleased to learn that she is a whore... j/k... ducking.
