I know that Norman is sometimes concerned about quiet spells on the Board.
I think is is natural. Sometime we have "done to death" so many issues that we take a pause.
I liken it to going to the pub with my mates. Often we have run out of things to talk about but then somebody walks in, we hear a new bit of news or a new moan or decide to take the mickey about something/somebody and off we go........!
