Actually, 'Sarah Plain and Tall' is purely fictional. The author came up with the story and its elements without drawing from real-life events or people.
Well, it could potentially be a story that focuses on Sarah, who is described as plain and tall. Maybe it's set in a virtual world or something. It could be about her relationships, her journey to discover herself in the online space. For example, she might meet different people online and through those interactions, she grows and changes. There could be themes of friendship, love or self - discovery within this online story.
In the full story of Sarah Plain and Tall, first off, Jacob is in search of a woman to be a part of his family. Sarah arrives in response to his ad. Initially, the family dynamic is a bit tense with the children being cautious around her. As time passes, Sarah starts to influence the family in positive ways. For example, she brings in new cultural elements from Maine. She teaches the children about different kinds of plants that grow near the ocean. These interactions lead to the children accepting her more and more, and finally, she decides to stay and become a permanent part of the family.
The story of Sarah Plain and Tall is set in a time when families were often in need of a woman's touch. Jacob, who has lost his wife, is looking for someone to help raise his two children. Sarah, who is plain but has a tall spirit, responds to his ad. When she arrives, it's like a new chapter begins for the family. Caleb and Anna are not sure what to make of her at first. However, Sarah shows them things like how to make a special kind of bread from Maine. She also sings songs from her home. These little things gradually break down the barriers. Her presence fills the house with a new energy. In time, she falls in love with the family and the prairie, and decides to stay, becoming a beloved mother figure to the children.
As the title implies, Sarah is the central figure. There could be other characters such as her online friends or family members who play important roles. Maybe there's an online mentor or a rival in the story that helps to drive the plot forward. But again, this is all speculation without actually reading the story.
Family is a major theme. Sarah comes into the family and has to form new relationships. Another theme is adaptation. She has to adapt to a new place and a new way of life. And love, as she gradually falls in love with the family and the place.
