Many people are misinformed that individuals who are as severely disabled as Michael have behavioral issues that are intolerable, and therefore believe that raising a child with such a disability would be a hassle. When in reality, all it takes is a little bit of patience to understand where their behavior is coming from, and doing the best to alleviate their discomfort.
As for Michael's behavior, he's a pretty calm and serene kid. He loves peaceful environments, listening to music, and being outdoors. He really hates loud screaming, but has significantly improved in loud environments. During fire drills at school Michael used to get irritated by the loud alarms, but has now effectively learned to stay with the class and keep calm with the rest of the students. All it takes is a little understanding of the situation behind a misbehavior flare-up, because in most cases, many of these individuals are not much different than you or me.
