“In giving a gift, you are attached to it. In receiving a gift, the blessing that comes to the giver is your chief delight. And the you that is attached to the gift that is given is either a gift just like the physical gift, or it is a booby-trapped box full of hidden emotional expenses. Do not be like the woman that C.S. Lewis said lived for others — and you could always tell who the others were by their hunted expression” (God Rest Ye Merry, pp. 102-103).
