I chose other, because I am the outsider/outcast. I have very a very hard time finding people I can get along with, and who actually want be around me, otherwise they will ignore me. I'm a nice person, and I can get along with just about anybody, so it's kind of odd that nobody wants to around me, at least in the long run.
Nobody ever wanted to be anywhere near me, besides my family, mainly because they're outsiders too. Even when I was a little kid, I was viewed as some sort of abomination, and wanted nothing to do with me. These people made sure that I knew that I was an outcast, shunned, hated, and I should be destroyed.
I never really had any friends until recently, and I'm twenty years old, and in college. Over time, I started to think that maybe the reason people don't like being around me is because I have very powerful energy field (aura) around me. One of my friends said that when they first met me, they felt very uncomfortable, as though they were being suppressed.
An excellent example of trying to understand of how I felt is H. P. Lovecraft's short story "The Outsider". It gives the closest idea of how I felt and how people seemed to treat me.
