It seems a great big hole to me,” squeaked Bilbo (who had no experience of dragons and only of hobbit-holes). He was getting excited and interested again, so that he forgot to keep his mouth shut. He loved maps, and in his hall there hung a large one of the Country Round with all his favourite walks marked on it in red ink. “How could such a large door be kept secret from everybody outside, apart from the dragon?” he asked. He was only a little hobbit you must remember.

Never laugh at live dragons.

I desired dragons with a profound desire. Of course, I in my timid body did not wish to have them in the neighborhood. But the world that contained even the imagination of Fáfnir was richer and more beautiful, at whatever the cost of peril.

It simply isn't an adventure worth telling if there aren't any dragons.

Getting rid of dragons is not at all in my line, but I will do my best to think about it. Personally I have no hopes at all, and wish I was safe back at home.
