The situation you mentioned raises concerns about personal boundaries, privacy, and autonomy. At the age of 15, individuals are typically entering adolescence and developing a sense of independence. It is essential for teenagers to have their personal space and privacy, including when it comes to personal hygiene activities like showering or bathing.
Requiring a father's presence in the bathroom during bathing can be inappropriate and may potentially lead to issues related to boundaries and emotional well-being. At this age, young people should be encouraged to handle their personal hygiene independently, which helps promote self-confidence and self-sufficiency.
If your friend feels uncomfortable or concerned about this arrangement, it may be helpful for her to discuss her feelings with a trusted adult, such as another family member, teacher, counselor, or school nurse, who can provide guidance and support. It's crucial to ensure that young individuals are safe and supported in their personal development. If any potential issues or concerns arise, it's best to address them in a caring and appropriate manner.
