Or you would have to question by what their standards are for 'being nice' to begin with. If you're not willing to make a move and then complain that nobody pays attention to the 'nice guy', it would be because you never made that bold move that many of us would need to begin with... Nobody is guaranteed or granted anything to begin with, no matter how nice or mean they are...
Then again, what do I know? I don't like anybody.
