I'm eccentric basically, sometimes downright weird (as said by most people) due to my interests are not common. I'm introvert by nature, that's why many people at first glance think I'm a snob. Which I'm not, by the way.
I'm usually quiet but when I'm with close friends & relatives, I'm quite a chatty & cheerful person. Not all people are what they appear at first glance.
BTW, I'm bi, just putting it out there.
