Swearwords

Hey, what’s up, shitbreaks! …Oh, excuse me…
I want to write about swearwords before I leave Adam’s class.
I bought this book some months ago. This is so interesting and I can learn lots of swearwords from this book. This book may be disgusting for some people but I respect the author. Only this book can make me feel good while reading. Novels? Piss off.
Since I’ve started to study English, I feel a great interest in English swearwords. Many American young people speak swearwords regardless of their sex as far as I know.
Also, I hear dozens of swearwords in an American movie and music. However we can never learn swearwords even in communication classes at school in spite of that fact. What I want to learn is just what Americans do. Though swearwords are obviously part of English which Americans always speak, we can’t learn them, no teachers teach us about them. Why? If we go to America without learning swearwords, we’ll be in trouble because we don’t understand what Americans mean. Also when you are with your American friends, you’ll never spend time without hearing a swearword. So swearwords are important for English learners. What do you think?

PS. I know teachers try not to speak swearwords but I (we?) want teachers to speak them in class, and I also want to speak them though I have no idea whether teachers accept that or not.
