The following text is from Lucy Maud Montgomery's 1908 novel Anne of Green Gables. Anne, an eleven-year-old girl, has come to live on a farm with a woman named Marilla in Nova Scotia, Canada.

Anne reveled in the world of color about her.
"Oh, Marilla," she exclaimed one Saturday morning, coming dancing in with her arms full of gorgeous boughs, "I'm so glad I live in a world where there are Octobers. It would be terrible if we just skipped from September to November, wouldn't it? Look at these map branches. Don't they give you a thrill--several thrills? I'm going to decorate my room with them."
"Messy things," said Marilla, whose aesthetic sense was not noticeably developed. "You clutter up your room entirely too much with out-of-doors stuff, Anne. Bedrooms were made to sleep in."
