Was it the shock of suddenly being outside for the first time, today? I'm not sure. But it was very quiet. Cars purred by softly on the main road. Even passing aircraft seemed a bit further away, a bit less harsh. The sun beat down on the concrete under my feet. I wouldn't be out for long.
On returning, I poked around in the cellar at our sump full of water. The cat danced around the hole in the floor above me, wondering what I was doing, and how he could get down to investigate. I drained as much as I could, wondering how a whole room could stay so damp on a day so hot and dry outside.
