From an early age, I have never quite felt like I belonged or that I was even a member of the same species as other people. As a child and throughout early adolesence, for as long as I remember, I had been angry with "the world" - not with anyone in particular, but with the way society operates. When I was perhaps 9 or 10 years old, I began to seriously question whether everyone else was an alien and I was the only human. In actuality, that would have made me the alien.
This sense of alienation lingers to this day, as someone with absolutely no interest in parties, drinking, drugs, money, material possessions, and the hedonistic lifestyle in general, but I've adapted, living quite a fulfilling life, and get along rather well with others despite our differences.
I'm generally not entertained by entertainment. I live a very sober lifestyle. I'm celibate. I meditate excessively. Others have mistaken me for mute, enlightened, a genius, and an "old soul" - none of which I can agree with (except for perhaps the mute part - for a while in my childhood I barely spoke to others).
Overall, I'm not quite human, but I can live with that.
