Your're Ugly Too-Zoe

Zoe is an interesting character. SHe always has a sarcastic attitude that becomes prevalent in almost the whole story. She makes jokes and teases by fun. Her favorite joke which includes the title is "...I want a second opinion, your're ugly too." She tells this to Earl. It is strange because Zoe feels as though she can tell Earl everything even though she just met him, yet she can not even tell her sister. In a way, I feel Zoe is estranged in someway. She has weird thinking habits and places all of her items in her perse individually in baggies. I think she does this show that she can keep everything seperate and in order. At the end of the story, she acts as if she is goign to push Earl over the side of the building. What possessed her to do this? She was just joking and she says that over and over, yet there is a part of me who wonders is that true?
