Addendum...

I've just lost the plot entirely, and been bad.

It was the sight of a pasty, warm from the oven, that did it. Yes, I'd already eaten my lunchtime orange and a bowl of muesli (with skimmed milk for gawd's sake) and only went to the canteen for a cup of tea. But there it was, all flaking pastry and golden.

It wasn't even that nice. Mea culpa!
