Hello Silvia. I wonder why you used "voi" in your answer? I would certainly have put "tu". These phrases of Morris's are like horoscopes, and I see them as addressed to an individual. Although I suppose one could imagine saying "You Scorpios are intense" and so on. I know that "voi" can be used to a single person, but that's not a normal usage nowadays, is it?
Sorry Rob, I omitted any further explanation because morris is translating a book about numerology, and he's translating everything as addressing public, thus voi. Voi used for a single person is very very oldfashioned and used mainly in some dialects. As an example, I know that one of my (acquired? I don't know the proper word) uncles, who's 60 something, addresses his mother with vu (he's originally from Cremona). Weird uh?
