Yes, there used to be some differences in dialect and culture that made communication somewhat difficult. In modern times, hardly any more, especially not in the
cities. But the cliché has remained and people on both sides like to make fun of it.
I definitely like dialects, and there are a lot of them in Germany. At the same time, unfortunately, they are disappearing faster and faster. The younger generations hardly speak any dialect anymore.
I only came up with this because the
hobbits somehow remind me of the former Bavarian rural population, similar to how - as originally intended by
Tolkien - they were supposed to reflect an idealized, English rural population from times past. They are down-to-earth, work a lot (if by chance they haven't inherited a
dragon treasure), but also value comfort and coziness, good beer and like to party. And are hardly interested in what's going on outside their borders.
