I have also been told that I am apparently too intense/strange for my own good, maybe yours too? I essentially lack a "normal" social filter. Most people tend to get turned off by the frankness in my demeanor. I do have no true social filter though. Perhaps you will give me a chance for more than five minutes in which you are making an instant characterization without much foreknowledge.
**Edit** Feb 5, 2014:
My Groundhog Day (a lil late for New Years) resolution is quitting a filthy disgusting habit that I burned *over* half of my life away into the hands of the lung cancer Gods. So I am now on day three without even a puff of a cigarette :)
