Our almost-spring has reverted to winteriness today, so it’s back to the old Africa album for Square 22 and a bit of midday heat. Am imagining too the smell of the bush – spicy sundried grasses and hot peppery earth – and in my head the seamless kroo-krooing of doves. And because it has amused me ever since I heard it from a tipsy guide in Zambia, I make no apologies for repeating it again here: when it comes to zebras’ butticles, he told us, each has its own unique set of stripes. He further suggested that this was how the offspring recognised their mothers. I have no idea if this is true, but am happy to go along with it if only for the butticles, since they sound more decorous than buttocks and so have remained discriptor of choice in the Farrell household when referring to that particular part of the anatomy. And anyway, zebras do sport such very handsome ones.
