It is possible that your sister enjoys pampering herself because it makes her feel good and helps her relax and de-stress. Engaging in self-care activities can be a way for her to prioritize her own well-being and focus on herself, especially if she tends to put others before herself. It's important for everyone to take time for self-care and prioritize their own needs, so it's great that she is able to do this for herself. If it becomes excessive or starts affecting her responsibilities and relationships, it might be worth having a conversation with her to make sure she is finding a healthy balance.
