Who is Susan Greene from The House Next Door and what is their importance?

Susan Greene is a member of the third family that lives in the haunted house. She is the wife of Norman and mother of Melissa. Susan became pregnant with Melissa before she was married. Although her own family kicked her out, Norman agreed to marry her. Norman is cruel to her, but Susan lives her life in such a way as to show her appreciation to Norman. While Susan is generally a very organized woman, she suddenly loses her ability to organize her life or keep her house in order when the Greenes move to the haunted house. In addition to the loss of Susan's ability to organize, Susan's daughter also becomes very sick, another factor that distracts Susan from her housework. For the first party that Norman forces Susan to host, Susan forgets to contact the power company about some electrical problems the couple has noticed in the house. When the power goes out during this first party, Norman blames Susan for the resulting catastrophes. It is after their second party, for which Susan forgets to mail the invitations, that Susan kills her husband, her daughter and then herself.
