Please give me three ideas to write a critical essay about Haunting and the effects of its employment on the representation and assessment of different social and cultural aspects in The Little Stranger by Sarah Waters.

One idea you might want to address is the way in which the family is haunted by what Roderick and Caroline believe is a malignant spirit. This haunting can also be seen as the family's being haunted by the ghosts of "proper behavior" once assigned to elite families. This example supports social and cultural aspects, in that, it was believed that elite families should be an example to the lower classes, and as such, it was not generally accepted for a member of an elite family to be sent to a mental institution.
