Why is molly the protagonist in the book wait till helen comes?

Defnitions:

Antagonist: The enemy ( You can remember that by saying -anta-go-nist- or anti-go-nist, and we all know what "anti" means. )

Protagonist: The main character ( You can remember that by saying -pro-ta-go-nist, and we all know the meaning of "pro". )

So, Molly is the protagonist because she is the main character. If you actually read the book you would know why. :-P I hope you get it now. LOL :-)
