On the long train journey north, Harry Potter meets the two people who are to become his best friends, Ronald Weasley and Hermione Granger. Ron and Hermione have very different characters. Hermione, who comes from "Muggle" (nonwizard) parents, is very intelligent and talented. She is such a know-it-all and so bossy that the boys do not like her at first. Ron, on the other hand, comes from an old family of wizards. He is number six in a family of seven children. He wears hand-me-down clothes and even his pet rat used to belong to his brother Percy. Ron knows all about Harry Potter.
