It's one of the most difficult things to describe yourself - but I'll give it a go anyway:
I'm a music aficionado, an avid reader, an introvert, and a very curious person.
By nature, I'm a hedonistic materialist and a rather cynical realist. So, I tend to come across as discourteous, brusque and a bit of a prude, on a first encounter. That changes, however, once you get to know me, assuming, of course, I do not develop a dislike towards you.
But then, self descriptions are generally inaccurate so you should start wondering why you wasted your time reading this. Or you could find something productive to do.
