Its not that I lack social skills. I certainly work at a fairly social job, making friendly, confident interactions with people all day.
I'm also not a recluse, who spends all his time in his apartment browsing the internet and masturbating. I like spending time outside, especially in the few natural parts of this city that haven't been paved over.
I just find people completely uninteresting to be around. My work is really all I can handle when it comes to socializing each day, because I just get so sick of having to stoop to that level. People are just naturally insipid and puerile, completely ruled by their back-brain emotions and devoid of the capacities of critical thinking. When you do meet the occasional person who isn't, most of the time they have some sort of crippling social ineptitude that makes them unbearable to be around.
Being reclusive just means I don't have to deal with that.
