People who boast about how much they read and/or how many books they buy, like 'being a reader' automatically makes them some kind of superior being.
Of course not everyone who reads a lot is like this, but there is a definite 'type' who do this, and they're really annoying.
There is also the type of person who brags about what type of books they read. I find this really annoying as they tend to look down on the type of books they don't find worthy. I have known people who find out I read bestsellers ( I really like Stephen King and Tess Gerritsen) fantasy and Christian romance like those ones set in Amish country that I am stupid. Its not reading unless you are reading high literature non fiction or classics. I don't care what people read or don't read unless its something we both do and can talk about it together.
I hate this too. I ready pretty much anything that looks remotely interesting, and that strikes my mood at any given time. So fiction, non-fiction, some romance, some YA stuff, mysteries, etc etc etc. The only thing I'm not really that into is Westerns and most sci-fi/fantasy. I have gotten into some, and am trying to broaden my horizens, but I'm like the guy in the one Twilight Zone episode, just not enough time.
I have a family member who ONLY reads non-fiction and history. WHich is great, but she kind of thinks she's superior to others since she "learns" and doens't read any fiction. Whatever, but that certainly doesn't make you any better than anyone else! We're close enough when she starts in with that, I then remind her she watches every trashy reality show out there....
