In the beginning of The Hobbit, the city of Bilbo shaped his character in several ways. One way is that Bilbo, being a small and timid hobbit, was accustomed to living a quiet and predictable life in the Shire. However, when he is thrust into the unfamiliar and adventurous environment of Bilbo, he is forced to step out of his comfort zone and face numerous challenges.
