My friend's little girl firmly believed Rikki Lake (yes, the chat show hostess) was her best friend. she'd sit there and have whole conversations with Rikki and couldn't believe no-one else could see her.
she also had another imaginary friend called Goosy Bambi and an imaginary fox friend called Trevor.
