A thoroughly interesting read this morning, and a timely one, as I have cleared off to the study with my coffee, whilst my guests roam about downstairs showering and organising their day. I love them and their kindness, and it's lovely to see them, but am in no doubt about my ambiguity in having them stay here for 10 days. 
Yes, a good essay, and one I'll read again, when the need to disappear for a few minutes arises again!
