"(Losing your mind is ...) such a silly turn of phrase. It implies it's somehow your fault. It suggests you were being careless, or became distracted along the way and mislaid it somewhere, like a set of house keys, or a Jack Russell terrier. Or a husband, perhaps. Although I suppose losing your mind can prove quite helpful sometimes, because it does hint there is a possibility, however slim, that you may find it again."
From Three Things About Elsie by Joanna Cannon
Wonderful novel about dementia, I suppose, but so much more than that with a heroine whose side you are on all the way. Unexpected endings - in the plural because there's more than one I feel. ****
