Today has been a day of swings from yins to roundabout yangs. Some favourite things – sunshine, watermelon, friendship – and others not so tip top: wind skipping up sand, warm water and jellyfish in the shallows. But when the rain came and there was one umbrella for all of us, how many could take shelter? All of us, of course, because that is always the answer. All of us, together. All of us.
