I don't know you well enough to offer you an answer to that question that you should even consider taking notice of.
For what it's worth, you certainly don't strike me as a 'bad' person. Sure, perhaps you could do with focussing on positive stuff a bit more but to be honest I think there's something built into us that can lead that to happen. Ever noticed how good memories seem to have a shelf life whereas the bad ones never seem to go away. I reckon that's because we LEARN from the bad ones so they tend to be more vivid so that we don't make the same 'mistakes' again and again. Having fun is more like a drug...you need to go back for more. Of course, that's just my brain ticking over into amateur psychologist mode. Take as little or as much notice of that spiel as you wish! After all, what the hell do I know? I'm just a fellow human being trying to muddle way through the time I have on this here green and blue ball.

As for being antisocial...in my humble and honest opinion, people who feel the need to spend their every waking moment socialising and maintaining a greater number of shallow friendships as opposed to a few strong and meaningful ones are either running away from something or lacking something within themselves. Of course I would say that being somewhat of a hermit at heart. I'm sure those people would argue that they're merely trying to enjoy every moment of their lives. I guess it depends on what you want from your life. If was busy all of the time, I wouldn't be able to amuse myself by thinking ridiculous thoughts like these or writing 'awseome' (HAH!) poetry or sitting back and having a look at how the world REALLY works outside of the realm that homo sapiens has created for her/himself.
Liking your own company doesnt make you a bad person. 'Actually' liking Katie Price or wanting to eat people does...*cough* not mentioning any names of course!

[Good grief! Just noticed how much I've written - sorry, I get carried away!]
