Many, many angry feelings.
I lived through the Thatcher years and it was not a happy time for the UK.
She was Prime Minister from 1979 to 1990 - I went to university in 1979 and I came to Japan in 1992, so that time was my adult years in the UK.
I never met "the Iron Lady", but those years as a student and then as a newspaper journalist were dominated by her image.
She DID change British life, and many of the changes were necessary - but it was a hard time for millions of people.
She is admired in Japan as a tough leader etc. However, I think if she became leader of Japan today her policies would shock many Japanese people who have a comfortable life. There are many problems in Japan today and Japanese politicians are too afraid to make necessary changes...so they do nothing.
Margaret Thatcher never did nothing. That's the best I can say :-)
