Thanks to all those who picked up this seeming error, but the time line is very close They started university in 1968 they were in France in at the end of their third year. This means the summer of 1971. However I have changed it to francs to avoid further e mails. I have changed it to francs in a repost to avoid further emails. I have also corrected two other small typos which were pointed out to me I will check the time line for beginning their university career and post it in a further chapter so that everybody is clear where our dateline currently is in the story.
