I'm completely fucking isolated. Like, a million miles away.
Someone at work invites me to a party. I go, I have fun. I never get invited again. New person gets hired, pattern repeats. Reliable as a clock.
My wife? I picked her up using techniques from the seduction community, which I studied like a science and practiced for over a year. I did that because I was tired of being a virgin, now I hate this relationship and feel powerless to escape it. BTW, during that seduction community time I spent endless hours at bars and clubs, surrounded by people having fun and pretending to have fun myself. I never had any fun there. It was more of a war zone which I tolerated in pursuit of a goal.
At work I feel like the mythical Cassandra, cursed to see the future but no-one will believe you. (I'm a programmer, of course.) I wish I could just treat it like a job that doesn't matter, and that it wouldn't physically pain me when some idiot can't even follow in-house variable-naming conventions, etc.
Sure, I guess I can't be 100% certain that fry-cooks aren't in their own screaming hell, just like I can't be 100% sure I'm not living in Plato's cave. But I think that's pretty fucking academic compared to the above things which I can be sure of.
