Kate Atkinson said this quote

She was tremendously fond of Ralph. Not hounded by love the way some women were. With Crighton she had been teased endlessly by the idea of it, but with Ralph it was more straightforward. Again not love, more like the feelings you would have for a favorite dog (and, no, she would never have said such a thing to him. Some people, a lot of people, didn't understand how attached one could be to a dog.)
