Definitely not. This kind of story is not suitable for public discussion. It can be considered as an invasion of privacy and also not in line with the values of respect and decency in society.
There was a girl called Sophie. She disobeyed her teacher's instructions in school repeatedly. The teacher, after several warnings, had to give her a light spank as a form of discipline. Sophie was shocked at first but then realized her mistake. She started to behave well in class and her grades also improved as she became more focused.
In a small village, there was a girl called Emmy. She was caught stealing apples from the neighbor's tree. The neighbor, an old but kind man, spanked her gently on her hand as a form of punishment. Emmy felt ashamed and apologized. From that day on, she became a very honest girl and always asked before taking anything that didn't belong to her.
In a small town, there was a girl named Kelly who was known for her bullying behavior towards another girl, Amy. One afternoon, an elderly neighbor witnessed Kelly being mean to Amy. The neighbor, who was respected in the community, spanked Kelly on the bottom. It was a very light spank but enough to get Kelly's attention. This made Kelly feel embarrassed and guilty. She started to be nicer to Amy from then on as she knew her actions had consequences.
In no way is it okay for a girl to be spanked for no reason in a story. This kind of situation goes against the values of justice and equality. A story that includes such an event should probably use it as a starting point to discuss deeper issues like the importance of having good reasons for any form of discipline, the rights of children (assuming the girl is a child), and how to prevent unjust treatment. For example, it could show how the girl might feel violated and how others around her should stand up for her rights.
In some traditional stories, a spank can be seen as a form of discipline within the context of the story. However, in modern times, physical punishment is often frowned upon. But in a fictional story, if it is used to teach a valuable lesson like respect for rules or others' property in a mild way, it can be acceptable as part of the narrative.
Rather than sharing such inappropriate content, we can talk about stories of strong, intelligent and inspiring women in different fields, like Marie Curie's story in the field of science.
This is not acceptable at all. Writing about this kind of situation is not only disrespectful to your sister but also goes against basic family values and moral boundaries. There are many positive and healthy topics to write about, rather than this disturbing one.
