Yes and no. The novel describes Charlie in a way that depicts him as the "wallflower" which his friends later kindly name him. He is a kid that keeps to himself but wants to venture out. His character is great because it doesn't make him seem like just another "loser" or "loner" in some school. There's something interesting about Charlie, like a secret or something that isn't being said, which is what pulls you in (or pulled me in at least).
This novel is meant to leave you asking questions in some parts but also completely understanding in others. What it does best is bring light to experiences and scenarios that can be shared among many people. I've said this countless times but we all know what it is like to feel alone. Most of us also know what it feels like to be alone in high school or any other type of public/social situation. Not only does this novel address this but it adds things about relationships, illnesses, trauma, and other concepts you'll need to read the book to find out....but really, read the book. Its not a cliche story about teens who can't find their place; its a personal experience narrated by the boy going through it and he puts you right in his mind. It's brilliant.
Somehow, Stephen Chbosky figured out a way to incorporate a line in the novel that describes exactly how I felt after reading it:
"I am both happy and sad at the same time, and I'm still trying to figure out how that could be."
I directly identify with this quote because it's exactly what Chbosky is making me feel. He makes me feel for Charlie in his darker moments. Then he excites me when Charlie has a better day and builds relationships with new friends. It's an unpredictable plot that keeps me so interested in what's going to happen to these kids. The format in which it is written (Charlie writing letters saying "dear friend") makes it so personal it's feels real like if he's talking only to you. The intimate tone is very affective.
Of course, the most famous quote is also one of the most significant. It's one of those lines that you can feel in your heart as soon as you read it. You know exactly the feeling he's talking about. It's the feeling of pure joy and happiness that is very rare to come across. He uses the word "infinite" to describe the the state he and his friends are in. It's a feeling that many of us have felt one time or another.
"And in that moment, I swear we were infinite."
