Never mind, we are both quite old, we shan't live to see the worst, let us cultivate our gardens as best we can — tell me what plants you want from mine, and which you would like to offer me from yours, and we shall remain contented and affectionate.A graceful variation on a famous phrase from Voltaire's Candide: "Il faut cultiver notre jardin."
Hat tip: Ian Jackson, who has offered me so many plants from his garden.
