What is a quote from the book about Bilbo's actions , and what does it show about personality?

Sorry! I don’t want any adventures, thank you. Not Today. Good morning! But please come to tea – any time you like! Why not tomorrow? Good bye!”

This quote sets tone and character for Bilbo. Bilbo is a Hobbit and hence craves a life of peaceful routine punctuated by the visitings of Gandalf. Bilbo longs for this life through the book but does change into a more adventurous and daring Hobbit.
