Before the summer becomes a distant memory there's just time for a quick catch-up. First week of August: we all got on a plane to Berlin, to stay with Julie. I realised over dinner one evening that we had known each other 25 years. That's just a tiny bit frightening. But the weather was great, Berlin's Tierpark was fantastic, sandy playgrounds were almost like the beach, and open-air swimming pools under blue skies made it feel like a real holiday.
