Montaigne offers a top tip for he (or she) who would keep themselves sane:
That man, in my opinion, is very miserable, who has not at home where to be by himself, where to entertain himself alone, or to conceal himself from others.
When at home, I a little more frequent my library, whence I overlook at once all the concerns of my family.
Surely this is why men have sheds. A man needs his ‘domain’ however small. Given our postage stamp-sized garden, the kitchen by night largely serves for me. But a shed one day would be nice. As for a library, a man can dream. Lucky old Montaigne.

M Montaigne is usually pretty clear, but the first time you pointed this one out, I took the opposite meaning: as in to oversee or look over in a supportive, family nurturing kind of a way. Understanding better the real sense, this fits, particularly with the concentric circles of self, family and world beyond. Which I have been trying my best to practise from my i cloud shared documents library. It’s the way of the future, y’know.
