Have you ever agreed to do something without thinking through what it actualy means?

The other week Lisa Lewis from the Doorway Project, a homeless charity in Chippenham, rang me and asked if we'd publicise a sponsored sleepout in St Andrews churchyard.

I said of course we would and then she asked if I would be doing it. Before you can say dog on a rope I'd said yes.

Now, this Saturday, instead of cuddling up with a glass of London Pride in front of Match of the Day I will be lying on damp grass in a sleeping bag, telling myself to keep my mouth shut next time somebody calls.

I can't think of anyone less suited to sleeping rough, well, except maybe the Queen, or Stephen Hawking.

Me and camping go together like gas leaks and fire eating and that is with a tent around me so lying out in the open in January is not my idea of a great Saturday night out. But I suppose that is kind of the point...
