I’m not good at numbers; words are more my thing but I dabble in statistics and the mathematics of probability. Chance I call it. I’m not often alone. Not often silent, except that companionable silence when you’re lost in your thoughts, but in good company. Surprised all at once by a squawk, a solitary moorhen deep in the reeds, minding its own business, today I’m out practising, sitting alone in the sunshine. Together, we come here often, striding up the cliff-top, dawdling through Kensington Gardens, pointing out fading displays of dahlias and falling leaves. We order americanos at the cafĂ©, with a jug of hot milk on the side – ‘that’s hot milk, please’ – to make our stay last a bit longer. Today, though, it’s just coffee for one. I consider a cappuccino, a break from routine; old habits are hard to break. ‘Americano’ I say, ‘with hot milk, please’. Would I change if I were left alone? The moorhen seems content. Does it ponder the meaning of life? A seagull soars into the blue – doe
