How well do you know the character Melinda Gordon?

Ghost Whisperer's main character, Melinda Gordon, can see and talk to the dead. She acts as the middle woman between them and those still living, helping the dead move past traumatic memories and anger of what happened when they were alive. While doing so, Gordon gets the living to admit their wrongdoings as they go through a phase of bad events (retaliation by the dead). It's the show's premise, and nothing makes it spookier than watching it late at night. However, how well do you know the character past her work?
