Peter, are you as imaginary as your lovely tale? I googled you, and get the most interesting results. Peter Pansexual is the first. And then there's a Nigerian blog (Real Bubbler) that seems to attach itself to the article above for the purposes of the search even though It has never mentioned you in its life.
It has been ever so long since I read Robinson Crusoe, but I have a hunch the author did not let out any hints in the other chapters of how wise Friday is. I loved this.
