“The entire institution of gift giving make 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, where as you know what you need. Now I could simplify things, just give you the 50 dollars directly, and 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, is it worth it?”
