Question--
Who is the "we" you are referring to? I know that sometimes with Autism/Asperger's people (myself included) will use the word "we" instead of "I" but I just wanted to clarify if your talking about only yourself or if you are referring to yourself and others in your home or in your life.

As to the obsession, I know that other people with Autism/Asperger's often struggle with this and find coping strategies in therapy. It seems as though a form of therapy called Cognitive Behavioral Therapy seems to work well when dealing with this type of issue.
