There had been more inter-class movement than I remembered. At least one woman was now middle class, and Tony the cab driver was prosperous.
What I am really interested in is the characters, and I'll do a second post about that, using my favourite MBTI system to analyse them. I am impressed by the range of characters, how character is preserved but also changed as the years go by. It's beautiful.
And one can not help but be struck by what matters in life, and what doesn't matter. i won't belabour the point, but it's perfectly obvious from watching the show that some values endure and others fade. Also that strong people eat up adversity, while gentle people feel pain all their lives, but survive just as well as the strong do.
