Why is Shakespeare's writing shown in "Spanking Shakespeare"

        Shakespeare Shapiro is a very clumsy, antisocial, and sometimes stupid 18 year old boy. And "Spanking Shakespeare" is about all of his misfortunes that he encounters in his senior year of high school. And as we read about his misfortunes, we see that he is not very good at talking. And then we read some of his writing and it turns out that Shakespeare is actually very intelligent but he just can't convey this without writing. I think that the writing is present in this book in order to show the difference between  how clumsy and stupid Shakespeare seems to how he actually thinks.
        One example of this is when Shakespeare was trying to tell a girl named Celeste that he had a crush on her. And as I have described before, Shakespeare is not very good at talking, so as you might imagine, Shakespeare sort of messed up. He said "Uhhhhhhhhhhh... hi Celeste... ok bye". And that is it. But as soon as Shakespeare realized that he had messed up he began to write Celeste a letter. And this letter turned out to be so well written that Celeste asked Shakespeare out the very next day. This absolutely shows a huge difference between when Shakespeare Shapiro talks and when he writes.
        Another example of this is when Shakespeare is in class. As is shown throughout the entire book, Shakespeare when he is in class he is often bullied alot. And when he tried to stand up to a bully he ends up looking incredibly stupid. But then Shakespeare wrote that bully a note, and we don't know what exactly he said, but after the bully read that note, he never bothered Shakespeare again. As is clearly shown, Shakespeare's writing is much more convincing than his speech and it makes him seem much more intelligent then one would think after listening to him talk.
    Overall, I think that Shakespeare Shapiro's writing was included in this book in order to show an unknown side to the main character, and by knowing this specific trait about him, it allows the readers to get to know him better and thus feel more sympathy for him when reading about his troubles.
