Bilbo feels extremely unsettled at the thought of going on an adventure, for he had no time whatsoever to prepare for his journey. He wakes up late the morning he was supposed to meet the dwarves "at the Green Dragon Inn in Bywater at 11 a.m. sharp" (28). Gandalf hurries Bilbo out the door so quickly that Bilbo realizes that he has come without his hat, any money, or worst of all, pocket handkerchiefs, an omission that will worry Bilbo throughout his entire journey.
Hobbits are a folk who appreciate the niceties of life, like warm, snug beds and second breakfasts. Bilbo feels the loss of his secure little hobbit hole at Bag-End most keenly, and often comforted himself by "thinking once again of his comfortable chair before the fire in his favourite sitting-room in his hobbit-hole, and of the kettle singing. Not for the last time!" (43)
Thankfully, Bilbo inherited enough adventurous spirit from the Took side of his family that he adjusted fairly well to life on the road. In the first leg of their journey when the company still traveled through decent lands and had plenty of supplies, Bilbo "began to feel that adventures were not so bad after all" (29).
At first, he feels intimidated and scared which is partly because he is a very non-adventurous person. He also gets homesick along the way but afterwards, he starts to get more comfortable.
