I do, and I don't at the same time. If people dislike me for valid reasons, then I really have no control in the matter, and shouldn't care. Concidering that there are a large number of people that I don't like, it is only fair really. However, I do feel rather upset when I find that someone doesn't like me (and I did not predict it). I don't want people to get the wrong idea of me and dislike me for a wrong idea.
I really do strive to be liked by everyone though. I am also incredibly nosy, and want to know what everyone thinks of me, just for the sake of knowing.
