Why did aunt willie look after sara and her syblings in the summer of the swans?

Aunt Willie looked after Sara and her siblings in "Summer of the Swans" because their parents were preoccupied with their own issues, leaving the children in need of guidance and support. She stepped in to provide a stable presence, helping to care for them while also offering a sense of family and safety. Additionally, Aunt Willie's own experiences and wisdom allowed her to connect with the children's struggles, particularly Sara's feelings of insecurity and self-doubt.
