As a baby, charlie resisted being held and showed no interest in human stimulation. usually passive, he sometimes played with his wind-up toys but did not respond to his name being called and showed outbursts of temper if someone moved even one of his little cars from where he had placed it.
I think and arrange Charlie as having an autistic disorder, which can be grouped by impeded social association and correspondence. It is a neurological and formative issue that typically shows up amid the initial three years of life. A tyke with extremely introverted-ness seems to live in their own reality, indicating little enthusiasm for others and an absence of social mindfulness.
