Poco tempo fa trovai su questo sito una tesina che vedeva come argomento centrale le maschere, in anteprima c'era una nota frase di Shakespeare con allegata sotto una foto tratta dal film V per Vendetta, sto provando a cercarla già da un po ma non riesco a trovarla più e visto che anche la mia tesina ruota attorno alla tematica delle maschere, chiedo aiuto a voi per trovare quel file in modo da poter confrontare i collegamenti..grazie a tutti!

Last-born children, on the other hand, often have little responsibility, and they may be pampered as the "baby" of the family, but they are the smallest, and they have to get people to like them, so they often develop superior social skills.
