In Luis’ back garden one bright morning, he randomly brought out a couple of snakes he’d caught for identification and study purposes, before releasing them back to where he’d scooped them up. For God’s sake, let me take hold of one. Had I been body-snatched? On the brink of flinging it away from me in a trajectory as far as one could manage with pipe-cleaner arms, I held onto my teetering nerve along with the writhing creature. To calm myself, I called it Sally; now a ‘she’, I noticed Sally possessed the temperament of a purring pussy cat; and wasn’t actually writhing at all; rather, lay quite still in my hands. She didn’t even have teeth.
