Humans are social beings and are wired to live in families and communities. When a child or adolescent has a poor sense of social connectedness, they risk being excluded.
I explore this growth and development in all my books as it is the key to human resilience and personal success. Endless hours of playing with other children are still the best way to build social and emotional competence. No screen will ever be able to replace this and it is through hours of play, which will include episodes of childhood nastiness, that children work out how to be a good friend.
