When I first meet someone, unless they say something like "I am a monster," I think they are wonderful people. If they do say they are a monster, I think they must be sad and misunderstood.
When I meet an autistic person, something in me usually sings "Yay! They're like me!"
When someone meets me on the rare occasion that I am well dressed, well coiffed, wearing makeup and my nails are not a wreck, their first impression of me is of a vibrant, interesting, compassionate, attractive older woman. Then they get to know me and see I am weird as hell.
When I present myself to others in a more 'casual" state, they perceive me as weird from the get go. And they go out of their way not to get to know me better.
