Well, I changed. A LOT. I don't know if it was due to coming of age, or to some really bad health issues that happened in my family last year (fortunately they're over now).
The fact is that I'm not a cheerful Pollyanna person (and never will be), but instead I'm currently trying to look at the bright side of life - and it's working! :-)
I'm an introverted person (an INTP, for those who like this kind of personality tests), but it doesn't mean I hate people - I just like to be surrounded by just a few great friends than in a crowd. I value some time alone to be with myself, but simply love to go out with someone dear to me, too.
I'm not in OKC because I'm desperate to find a boyfriend/husband/friends with benefits/whatever, I'm comfortable with my own company :-) It's just that I guess it will be pretty fine if I could enjoy the company of someone compatible to me, and vice-versa.
