Asperger syndrome is noticeable when the person acts differently in social situations. Their social disabilities can have different levels. It’s not everybody who have Asperger syndrome that have the same level. This characteristic is not the only one. Someone who dislikes people in general does not necessarily have Aspergers. Other characteristics that can be identified are that Asperger people hate any changes in their routine. They also dislike having eye contact. Most of the time they will try to avoid it. They will look away. Usually people who deal with Asperger syndrome have less facial expression than anybody else. There are many characteristics, and if someone only has some of them then they likely don't have Asperger's. Commonly, people with the syndrome tends to hum or pronounce different sounds to themselves, which they have heard in their surroundings, such as a reporters's voice, a man on the radio, lyrics from songs, words, things they have read, or what people around them usually says. They may repeatedly mention these words or phrases again and again.
