Lack of self esteem at his core I believe. But it's defs getting better! I know it sounds daft, but a lot of Scottish people are brought up to mind and not get too above themselves.... it's our culture. I think Andy has had to battle that. And not that it's anything enforced by his parents.... just a cultural thing that exists. I may, of course, be speaking total pish! A poem by Kathleen Jamie 'The Queen of Sheba' sums up the Scottish condition nicely...
I'm not like that at all!
