St Helen’s Church was barely visible at 8:51 this morning because of the fog.

Traffic queued back along West St Helen Street. A minibus – full of children with hi-viz vests – was on its way to school. They were probably late, as were the people going to work.

The traffic slowly moved over the iron bridge from Wilsham Road and Caldecott Road. Some cars turned on Wilsham Road to try to find an alternative route. But everybody seemed patient and resigned to being a bit late. They let others in at junctions, and there was no hysterical beeping of horns.

Within an hour, the road traffic and the fog had cleared. Children were at school, adults were at work, and the sky was blue.
