It's hard to believe it's even the same child as 7 Up tbh, there must have been so much more going on in his home life because he'd already changed significantly by 14, much more than the others. By 21 and 28 he clearly harboured a lot of resentment for his parents.
I had read a bit of his story before starting the programme (hadn't seen any of them), and I was really interested to see him develop, but he was a frustrating watch. He seems to hold some very hard boundaries about what he will/won't do and what he considers intolerable. He drifted around the country, picking up casual jobs here and there and kept his head above water on benefits. But he seemed to believe that he should reject society, and he actually said that staying too long in one place and having a normal life would make him want to cut his own throat.
When asked about benefits and his lack of job (more of a stigma at the time), he said well it's benefits or crime, rather than benefits or stay in a job or stay in one place. He slept in sheds when he didn't have the money to find a bed, and at no point did he seem to think, 'I nearly went to bloody Oxford, I'm worth more than this.'
When he stayed with Bruce, he would just turn the fridge off when the noise was annoying him. And he'd have to leave the house and go for a walk when Bruce tried to hoover as he couldn't stand the noise. I can imagine him being a very difficult character to be around and he admitted to having a volatile and explosive temper. I think he always felt that he never fitted anywhere but so much of that was his own doing and refusal to adapt; he'd rather just move on and continue his insular life which then continued a cycle of depression.
I also noticed that his motivations didn't seem to really be about helping people, despite the eventual paths he took. In 21 he said he wanted to be in a position of importance, almost with an air of feeling like he deserved recognition. The stage work, the politics and perhaps even the lay preaching (I'm only up to 56 so haven't seen the later ones yet), all seem to be about having a captive audience, rather than truly giving back to society and changing the world around him - a world that he of all people knows can be so difficult to navigate and survive in.
I found it really difficult to see him struggle as a result of his own choices, and possibly even more frustrating to see dramatic changes in his life between 28 and 42, which shows it was possible all along. He seems to be in a constant state of conflict in his own head.
