Another restless night. At 01.20 I stood at the window watching the skyline. During previous bouts of insomnia, there was always something faintly comforting about the long, probing lights of planes flying into Luton Airport from the east and descending elegantly behind the trees. Others awake like me, but in transit from Sofia, Talinn, Lyon, Kutaisi, Reykjavik, Cork. The enigma of arrival.

But in the small hours this morning nothing disturbed the skyline. And my sense of solitude was strangely heightened by the sudden doppler whine of a motorbike speeding by on the road below. But, of course, the solitude is real and its sense is pervasive. Yesterday we went for a walk. We crossed the fields and walked down the long slope of the lane. We were passed by just one car before turning onto the muddy track that took us past the farm and onto the bottom of the hill leading up to our house. As we walked alongside the meadow where the horses are grazed, half way up it a lone figure was slipping a bridle over the neck and head of a piebald shire horse. She turned as she gathered it into her arms and saw the three of us paused by the fence. With the solemnity of the stay-at-home edict still fresh in our minds, there was a curious hesitancy in the distant encounter. Then the woman slowly raised her free arm in a strangely stiff and formal salute; we returned it in similar manner; she turned and walked towards the stable buildings and we continued on our way.

So suddenly we’re strangers in a strange land. And as the economic structure purées all standard procedure around us, the normal social protocols go into suspension. In one street an act of inexplicable cruelty and stupidity occurs; in a parallel street the self-sacrifical kindness of a stranger demonstrates the extraordinary generosity that ennobles humanity in crisis.

And it’s all broken apart in a little over a fortnight. Here we all are inside our familiar house, moving from room to room, eating meals, binge-watching on Netflix, carrying our laundry upstairs, face-timing friends, sweeping floors, insulated briefly from the Mystery. But the outside world that we scrutinise through the windows has fallen away. The trees and fields and pathways prevail, but the few passers-by hasten in their transit as if anxious only to draw their own walls swiftly around them so that they too may themselves move from room to room, glancing now and then through the windows.
