Let's apply a grammar-checker to a piece of brilliant writing, Abraham Lincoln's Gettysburg Address. The Gettysburg Address <<_P7. IS THIS QUOTE CLOSED? *>>"Fourscore and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created<<*_S1 PASSIVE VOICE: are created *>> equal. <<*_S3.

Actually, fiction is not judged by standard rules of grammar. The mood and the images that the writer is trying to create are much more important in judging its quality. Even the most hardened English teacher accepts that. In this case, the story is being told by a young excited girl. Have you ever listened to them? They haven't changed since Lewis Carrol's time. Both adolescent boys and girls, but especially girls, tend to talk at a whirlwind pace, often sounding like one run-on sentence. I think this is the image and mood that Carrol was trying to create - successfully, I should add.
