Boudicca my dear,
if I were you I would suggest to say to your theoretical interlocutor to surf on www.stephenking.it, the marvellous Italian site dedicated to the King. :D
He would there discover how interesting and how funny the average SK reader is. He (the reader/fan) is enthusiastic about his/her preferred writer, knows the details of his private life and, above all, wants to share his/her emotions with everybody else. He/she has developed also, starting from SK novel, a genuine curiosity for the different aspects and "nuances" of life especially the every-day life of each of us: the dynamics within the family, the neighbourhood, friends, music, religion and mind-set.
And, if it is not enough, you could mention how important the irrational side of the human being is: how easily everybody can slip into madness and despair but also how each of us is close to be a better fellow able to feel and sympathize with the rest of the world.
Therefore your interlocutor needs only a click to enter in the real world of imagination...
Allora, ti sono stato d\'aiuto? :wink:
A proposito, battute spiritose non sono ammesse... :evil:
