The story of three journeys I made in the 1960s, on both sides of the Iron Curtain. To Poland, with a group from the Co-op, as guests of the Polish Cooperative Society. To East Germany, with a group of kids from Lauriston Road school, where I was attempting to teach mathematics, to a class of kids, who would rather be outside playing football, or netball, or doing anything, but learning algebra, geometry and trigonometry. I must admit, I had some sympathy with their point of view. To Greece with my then girlfriend, Carol; who later became my wife. And later still, my ex-wife.
