Ok, that's not strictly true. I'm very friendly and polite, treat people equally, hold doors and smile at strangers. But...I'm often pleased when things go wrong for others (not major things like illness, but if they were to get a house that I would want to live in and it fell through, for example). My friend recently failed her driving test and I wasn't unhappy for her because I can't drive and she has made snide comments before. Next door's house is a tip which pleases me because it makes me feel better about my own and weirdly superior. My high school bully is now obese. Very satisfying.
Am I an arsehole? The reality is, I'm miserable and not where I want to be in life. Is this jealousy? I'm starting to dislike myself.
