If, weighing the circumstances, they infer that a book would indeed be useful to their child or friend, then, as a general counsel, I would suggest the giving of books that they read and admire themselves – not what an ‘expert’ recommends, because with a gift we convey also our own relationship with this gift, so that even on a good book, if we give it being ourselves irrelevant, we graft our irrelevance onto it. I remind that we don’t discuss about medical or legal knowledge, but for things that do not have their substance objective.
