Margaret Thatcher is giving a lecture on stocks and shares in an art school studio. There are only two female students in the room, the rest of the group has chosen to get on with their painting. One of the girls says she is not interested in making money, she wants to go to help people in Chad or Sudan. I admire her foolhardy courage. Thatcher - now the Queen - gives her a kiss on the side of her face. Do you think there will be a revolution when she dies? someone asks.
