Jo Walton has written an article on J.R.R. Tolkien’s The Hobbit and his impressions of it.
The unusual thing about The Hobbit for me was that Bilbo Baggins was a hobbit and a grown up. He had his own charming and unusual house and he indulged in grown up pleasures like smoking and drinking. He didn’t have to evade his parents to go off on an adventure. He lived in a world where there were not only dwarves and elves and wizards but signs that said “Expert treasure hunter wants a good job, plenty of excitement and reasonable reward.” He lived a life a child could see as independent, with people coming to tea unexpectedly and with dishes to be done afterwards (this happened in our house all the time), but without any of the complicated adult disadvantages of jobs and romance. Bilbo didn’t want an adventure, but an adventure came and took him anyway. And it is “There and Back Again,” at the end he returns home with treasure and the gift of poetry.
