Jenna: She is Aimee's eighteen year old sister. Their relationship is fine, but not the best. Of course the fight over silly things like clothes and who ate the last waffle, but they do have their sisterly moments.
Shane: He is Aimee's fifteen year old brother. They fight more frequently than he does with Jenna. They usually ignore each other and Shane can be easily irritated by Aimee with the simplest things.

Matthew: He is Aimee's biological father and happens to be forty-three years old. Their relationship is just like any other normal father-daughter relationship.
Anna: Anna is Aimee's biological mother who is forty-three. They are extremely close since Aimee took care of her mother throughout both of births of Jenna and Shane.
