The Perks of Being a Wallflower

When Stephen Chbosky wrote this book, it was surprisingly good that he aimed to address themes like sex, drugs, and abuse issues (physical and psychological) that can occur with teenagers.
The story is narrated through letters, and the first-person perspective allows us to constantly understand the character's feelings. However, at times, like the character himself, it becomes confusing to comprehend why the character acts the way he do. This confusion is resolved towards the end of the book, making everything fall into place.
In our lives, there are moments when we are like wallflowers—people come and go, some not sharing the moments we would like, and others we can't get along with, even among our close ones. Often, we accept the love we think we deserve. And we live by the others, not ourselves. However, we can always change. There's no perk of being a wallflower when you start to not live you life and missing the good opportunities to be infinity.
