I'm intelligent and don't hate my teachers: I must do well in school, and or am a complete prick.
(My grades are pretty much rolling a dice. And I'm only prickish to people who treat me so or arrogant idiots.)
I like games: I have no life and must play WoW.
(I've got plenty of lives! JK. I'm alive, and have friends. I don't play WoW, but apart from that, what's wrong with it? People have died playing it? 1 in a million is more of an anomaly than the rule. People get hurt and die more often in sports. If somebody does something for most of their time, guess what they're going to die doing. And even WoW causes online friends. You can't easily just cut players off from that.)
I speak to people on the internet: I'm anti social.
(What's anti social on basing friends purely on personality than looks?)
Stay in doors all the time: No life and hates the outside.
(I'm indoors a lot because I like games, and I don't have anything to do outside, because no one ever invites me to do anything and I never have idea for something to do.)
I have Aspergers syndrome and ADHD: I msut be overly hyperactive and require help.
(...I get offered help and extra time for exams instead of the dumb people. Most people don't even believe I have ADHD, because apparently everyone's an expert in it.)
I say I'm misanthropic: I must hate EVERYONE, FOR NO REASON. And I must hate life, and should kill myself to avoid being with people.
(I have reasons, and even though I hate humanity as a whole, I give every individual an individual chance...and then hate them. It's not my fault if they suck.)
Atheist: I must hate religious people.
(I don't hate them. I'm only going to get annoying if they annoy me by ignorantly disagreeing with things without any explanation apart from "God did it". I'm only going to yell if they do that or try to convert me. I can get along with logical people that are religious. I don't mind if someone talks sense, and doesn't hate science, and so happens to believe in God. I think Science and Religion could be compatible, even if God is powerful enough to be beyond logic.)
My vocabulary is better than yours: Must be an attention seeking nerd that reads the dictionary.
(No...and a thesarus would work better.)
