It's short, but the whole thing is incredible. Especially this:
Autism is not the terror, the disaster, the monster you have been taught it is. Autism is my hands flapping happily when a pretty song comes on, Autism is me staying up for hours researching my favourite topic, Autism is me quacking to communicate, Autism is the calm I feel when I’m in a small quiet dark room, Autism is me interpreting your sarcasm as literal, Autism is my mind shutting down when I have too much sensory input, Autism is me not recognising faces, Autism is feeling my emotions so intensely, Autism is so many of my experiences, positive and negative and a bit of both.
Autism is only difficult because we allistic people make it difficult for them.
