With my personal experience with Asperger's I find that I have extreme difficulties regarding facial expressions and sarcasm. I cannot differentiate or sometimes even recognize how someone is feeling based on body language. I have to guess solely based on their tone, which I only can identify basic emotions like anger or sadness. I have ended up alienating my peers, and as a result I only have a few close friends. Though despite all this I don't feel any different mentally, I only know all this based on what I have read, noticed, and been told about by non-autistic people.

That said, I hope this helps with your desire to learn about autism.
