Cornelia: "The body will become weak if all you do is read. You also have to exercise a little."
Mini: "Oh, it's book big sis."
Cornelia: "Ahh! Stay away! I'm not good with fire!"
Mini: "Read me a story, big sis!"
Cornelia: "Nooo! S-stay over there!"
Cornelia: "Oh, Page 17. Could you help me organize some books?"
Annie: "All right... Geez, Page 97 has completely dried out in this book..."
Cornelia: " And Page 211 has shriveled up in this one. The loss of interest in books has become really serious..."
Yoko: "Oh, Miss Page 65537. Have you come across any good books lately?"
Cornelia: "Actually, I just recently acquired 'Mrs. Shirley's Lover.'"
Yoko: "I'm so jealous... So, what do you think of it?"
Cornelia: "Of course, it's.... Fufufuu."
Yoko: "Make sure I get it next. Ufufuu..."
