B.P.
Have them come out to do a comprehensive evaluation. Sometimes what we think are strengths may not be and vice versa. Since you have concerns, they will come out and tell you if they are legitimate or not. Then you can stop worrying if he has a problem or not. Does he engage you? Does he tell you thinks he is excited about or respond appropriately to questions? Do you say his name all the time or not really? When you tell him about something you like, does he act interested? If only for a moment?
