How to Leave Hialeah

"You think, what does that even mean - poser?"

This line struck me as very significant in the text. It made me think: what is a poser and who exactly is a poser?

According to dictionary.com "poser" means, "someone who pretends to belong to a group only by affecting the attributes of the group."

So a poser is someone who does not really belong. But then, who in the group does really belong. Everyone in a group is usually portraying the attributes of the group. Is that not how one finds a way to belong anyway? Nearly everyone in life finds a way to mold themselves to a group but to do so, they need to take on the role or ideals of the group. Usually, joining a group changes a person, but that is usually is why a person joins a group, to change.

In "How to Leave Haileah", the speaker seems to not know where to fit in. She keeps changing and joining different groups. She could be considered a poser, but is it a bad thing? Or is she just trying to fit in somewhere and make a change in her life?
