I think your right, I think the reason that Mark wrote the series of books is to help kids who are different in that serent whay and I think that he probably never relay though that a lesbian character was neceserrary seing as he probably felt that any peorson could change the characters in the book and make it work for them. About perspective I think that the perspective in anyone ehter lesbian or gay is the same the felleing of being allone . But I think your right when you sed that a bie peorson could have defenetly made the books more interesting.

P.s.: I think that you probably forgot but there is a lesbian character in one of the books the one called a " Better pLace " but her part was kind of short .
