Autistic children who are high-functioning typically engage in repetitive thinking, including anger ruminations, constantly thinking about negative situations and angry feelings. These thoughts can lead to anger and meltdowns  Difficulty in starting up conversations - Socializing can be a challenge for anyone with autism. This is true for the Level 1 category as well. It's descriptive of someone not having the capacity to engage with other people in a normal fashion, oftentimes leading to shyness or introversion. Talking might be easier to do around family and other siblings, but strangers tend to be shied away from it. Additionally, having problems talking can morph into other problems if one isn't provided therapy to make them more sociable. Still, many with autism find it hard to dialogue, even those that are highly functioning.

Problems responding in ways that are expected - When someone with ASD does talk with another person, the response may not be what others around thought that it would be. What's spoken may come out as awkward at best, or indifferent at worst. Then there are issues with the autistic saying things that others don't understand, or might even find rude.

Problems staying with a conversation - Conversations are hard for the autistic, but many do try to have them. In the instances that they do, there could be an abrupt pause or disinterest in where it's going, then indifference.

Problems making friends - Although more know and understand what autism is, people that have it often struggle with friendships that are outside of the family. Their actions and demeanor can appear odd, or sometimes, off-putting to people that try to initiate conversation. When awkwardness is a factor, people generally shy away from it, and that's what makes it hard to form bonds with peers and co-workers.

Requires help in organizing - Mild symptoms usually involve a need for assistance organizing.
