“The entire institution of gift-giving makes no sense! Let’s say that I go out, and I spend 50 dollars on you, it’s a laborious activity because I have to imagine what you need, whereas you know what you need. Now I could simplify things, just giving you the 50 dollars directly, and then you could give me 50 dollars on my birthday, and so on until one of us dies, leaving the other one old and 50 dollars richer. And I ask you, is it worth it ?”
