People with ASD often have harder time understanding what other people might feel or how something might effect other person. That’s very very common for people on a spectrum regardless of their level of intelligence. In addition if a person has PD her ability to regulate emotions and impulses is impaired.

BUT it doesn’t mean people cannot learn what kind of behaviors are appropriate. Even if something doesn’t come naturally, it doesn’t mean it can’t be learned.

Unfortunately something is preventing ruby from learning it all these years.
