I'm going to take Iain Dale's advice - and not post a word about this expenses issue for the next week. I know it might carry on dominating our politics, and I might end up talking to myself, but when the atmosphere is so febrile, its very easy to cause unintended offence - which I've done without realising it. I do not want to do that - unless somebody's trodden on my toe too hard. Life's too short. So onwards to something different.
