I n 2004 a social researcher interviewed Rosa Keane and her husband Henry. How, they were asked, had they met? It had been decades earlier but, fortunately, they each had a clear memory. Unfortunately, these memories were different.
They both remembered how their encounter had begun: with Rosa slipping on some ice. And how it had continued, the two of them noticing each other shortly afterwards in a restaurant. But at this point the accounts diverged. Rosa remembers spotting Henry because he had odd socks. Henry remembered, instead, that it was he who spotted Rosa because she had two different colours of stocking.
