We used to live in a flat beneath a German man and his wife. One day he was telling us that as a student in East Berlin, he had a quiet night out with friends. He went to the cinema to watch a movie, came back to one of their flats for a few drinks, then they all fell asleep. He woke up the next morning to hear on the news that the Wall had come down. He’d been in Berlin the whole time and missed it.
