It's not my wish for you to avoid them. I would only hope that you would use them correctly. Learning and writing English is an on-going thing for myself. I'm assuming and hoping it's the same for others. We have been teasing you a lot lately and maybe that is a bit disrespectful, but seeing your reasoning behind it can be a little frustrating.
Why is that frustrating? Slang is often the basis for language change. I view it as a pretty high evolution of language use when you take terms understand their meanings, and use them with a subtle twist on the subject matter.
There are other 'sciences' that take common English terms and give them their own meaning. Really fun relearning the English language according to Psychology or Sociology. Law and medicine are guilty of the same redefining terms.
For that matter, Computer Science has done the same thing.
My girlfriend is currently taking a Political Science class at a local Junior College and her test seems to hinge on the author's redefinition of identity.
Kids do this all the time.
Maybe it wasn't critical enough.Sorry, but I've never experienced that a quality critical analysis harming my appreciation of a good book. If anything my experience is the opposite for I appreciated it even more as ideas that I didn't even consider were brought forward.
