Dogged by an acute appreciation of time | Dogs

My dog has a perfect understanding of time (Do animals experience time the same way humans do? Here’s one way to find out, 7 July). When it’s time to get up, he barks; time to eat, he walks to his bowl and stares at me; time for walkies, he looks up at his lead and will not move from the spot; and time for a chat when I shave. I dare say other pets have similar temporal acuity.

As a young GP, I remember assessing one patient’s memory with the standard tests (Letters, 8 July). It was only after he had left that I realised I had forgotten to check if he had recalled the address I had given. When we met again in a local supermarket, he reminded me of my mistake – and then put the boot in by reciting the address.

The first question of my sister’s in-hospital memory test was “What is your name?” The immediate and sharp retort was “Can’t you read!? It’s on the board behind me!” As indeed it was.

I was shocked by the suggestion that “Britain risks becoming a monolingual island”, in a letter from leaders in translating, interpreting and linguistics (7 July). Haven’t they ever been to Wales? A “monolingual island”? Dim o gwbl! (No way!)

Re Polly Hudson’s column (Do you need a word to describe how you feel in the heat? I nominate ‘natsubate’, 8 July), the term in my childhood in Cheshire was “puthered”, from which we have “puthery” weather, meaning hot and humid.
