The story of Elinor and Marianne seems rather incongruous with the rest of Austen's work. There is a lot of description of the countryside, perhaps in parallel to Marianne's tumultuous nature, and the Dashwoods are always going on walks up into the hills, down through the valley, over fields, along lanes, always walking. I've read this a couple times now, and as before was rather surprised at the youth of the main characters, especially having Emma Thompson and Kate Winslet in my head. They are only 16-17 and 18-19. No wonder Marianne's like that; it's pretty common for sixteen-year-olds.
