I think the following description of him may go some way to illustrate/amplify as to how the circumstances of his upbringing may have influenced (or had least may have had had an effect upon) the development of interpersonal and communication skills.
"An introverted, unusual young boy, isolated by his obsessions and a loner at school, Chris Packham was only at home in the fields and woods around his suburban home. But when he stole a young kestrel from its nest, he was about to embark on a friendship that would teach him what it meant to love, and that would change him forever. In his rich, lyrical and emotionally exposing memoir, Chris brings to life his childhood in the 70s, from his bedroom bursting with fox skulls, birds' eggs and sweaty jam jars, to his feral adventures. But pervading his story is the search for freedom, meaning and acceptance in a world that didn’t understand him."
