Yeah, I've noticed that too. Today I was commenting on how a job I did earned $87 in one hour and my sister had to immediately negate my sense of achievement by saying we already spent the money before the job was done. It's as if she can't bear to let any positive statement stand undefeated (and she accuses me of always being negative).

I also notice that things she says about me are more true about herself and I think about the mirror analogy. But I usually believe that people with low emotional IQ simply assign their own motives and feelings onto others because they aren't clever enough to imagine that other people can have thoughts and feelings that they don't have. So when my sister says I'm an idiot who lives in my own world and thinks I'm perfect, it sounds more like she's describing herself. I have never ever said I was perfect, but she claims that I say it constantly because her internal dialogue seems to drown out the actual words people say.

I finally understand another problem at college where she kept arguing with a professor that his quiz questions had meanings only she could understand. She hears what she thinks you are saying instead of what you really said. And she insisted during every class that the professor and the entire class failed to understand his quiz questions and only she was right contrary to all evidence. I guess it's hopeless expecting logic from someone who can't actually hear the words you are saying and I should find a way to stop being shocked by her behavior. Is it a sign of autism for an adult to keep interrupting classes innappropriately and not think they did anything wrong? I only know one other person who would do odd things in the middle of college classes and he had serious brain damage from an accident.

Thanks everyone for sharing your experiences. It helps to see the pattern to make make the behavior less personal.
