No spoilers please! I haven't got to the end of your book yet.
I like humour. Dry humour is even better. I appreciate jokes - if they make me laugh, then awesome. Hell, sometimes I even laugh at things that some people might not even think are that funny so I know what you mean when not everyone understands.
That woman was odd. She gave me American Psycho vibes from the first time I met her. Gosh, I watched that movie a few weeks back and it was so terrible. Were people seriously that weird over business cards?
I read the book American Psycho, decades ago, before I watched the movie multiple times. In fact, I watched a handful of books by this writer: Bret Easton Ellis.
The book is way better ( but pretty gruesome, very detailed ) than its movie adaptation, but the film is alright (imo). The business card scene can be found in the book too.
