I drove really slowly behind a tractor and trailer laden with huge straw bales. We ambled along with bits of yellow straw flying around, particularly as the tall wobbly load brushed past trees. Then we were slowed down even more: there was a horse and rider ambling along! I tried to look at the expressions on the faces of the drivers coming past the other way. Surely they'd be smiling in a sympathetic way.
It was a lovely moment. That phrase 'trailing clouds of glory' came to mind as that was exactly what was happening. No one hooted or got cross.
