Liz.....I know what you mean about the eye-contact thing. Looking away at something else and having to literally get into his field of vision......
That is a major feature of someone who has issues of focus...I have seen that many times with people who have adult adhd. They also can hyperfocus...for long periods of time when they are excited about something that they are very interested in. They can seem to live in their "own world" a lot of the time. that and lack of attention to detail...which they find too frustrating to their racing and easily distracted mind.
Now....just because I have said this doesn't mean that I am "right".
If this strikes a note with you....I would suggest that y ou read the book: "Is It You, Me, or ADD?". This most excellent book on the subject will, for sure, let you know.....
