Junie B. Jones and that Meanie Jim's Birthday

For my third outside reading I chose to read the book Junie B. Jones and that Meanie Jim's Birthday. The basic storyline is about a little girl, Junie, who seems to get herself in trouble alot. One day while she is at school, she makes fun of a boy named Jim and he tells her she is not invited to his birthday party that weekend. This upsets Junie because she does not want to be the only one in her class not invited. After they get in a fight and are sent to the principals office, Jim's mother makes him give Junie an invitation. In the end, Junie realizes she really does not want to go to the party and would rather play with her grandad instead. The moral of the story is that it is ok to be different and to be the only one not at the party. I think that these types of stories are good for kids to read; however, the one thing that bothered me was the grammar style Barbara Park used. She wrote the story from Junie's point of view and therefore used incorrect grammar such as "B is my bestest letter". I think this might teach kids the wrong way to write and speak correctly.
