The lady is kinda annoying. But the videos made me feel prepared and made me feel comfortable with my decision to not go to any formal classes, these were more than enough.

The Scarlet Letter is an interesting book. While reading the book I was filled with many feelings about it. I enjoyed some chapters, but loathed the ones describing the characters. I felt as if Hawthorne could have told the story more efficiently if he had described each character as they came onto the scene. The book made me feel inferior and uneducated. I made so many trips to get the dictionary that my legs got tired. I enjoyed the general story-line, but I could have left the adjectives behind. Pearl was my favorite character because she had a priceless intuition that helped me read the book. I would have been lost without Pearl's hints. I would not have read this book if not required to by my English teacher. Attack it if you dare!!
