Fiorella has always been interested in people who are different, i.e., interesting. If you come from another country or speak another language, Fio wants to get acquainted. If you have a story to tell, Fio will listen and congratulate or console you (although she also may use bits and pieces of it in her next book). If you have a special talent or skill, Fiorella wants to know all about it.
But she'll politely head in the other direction if you're boring.
