“How long does a mouse live?"
"Ah," she said. "I've been waiting for you to ask me that."
There was a silence. She sat there smoking away and gazing at the fire.
"Well," I said. "How long do we live, us mice?"
"I have been reading about mice," she said. "I have been trying to find out everything I can about them."
"Go on then, Grandmamma. Why don't you tell me?"
"If you really want to know," she said, "I'm afraid a mouse doesn't live for a very long time."
"How long?" I asked.
"Well, an ordinary mouse only lives for about three years," she said. "But you are not an ordinary mouse. You are a mouse-person, and that is a very different matter."
"How different?" I asked. "How long does a mouse-person live, Grandmamma?"
"Longer," she said. "Much longer."
"A mouse-person will almost certainly live for three times as long as an ordinary mouse," my grandmother said. "About nine years."
"Good!" I cried. "That's great! It's the best news I've ever had!"
"Why do you say that?" she asked, surprised.
"Because I would never want to live longer than you," I said. "I couldn't stand being looked after by anybody else."
There was a short silence. She had a way of fondling me behind the ears with the tip of one finger. It felt lovely.
"How old are you, Grandmamma?" I asked.
"I'm eighty-six," she said.
"Will you live another eight or nine years?"
"I might," she said. "With a bit of luck."
"You've got to," I said. "Because by then I'll be a very old mouse and you'll be a very old grandmother and soon after that we'll both die together."
"That would be perfect," she said.”
