I have a dog in my house who is loving, but very anxious when guests arrive. He barks at them. He is what people call a “rescue dog”. I like the way he feels, and he smells good, and we run together every day. He keeps me company as I write. But it is hard to entertain guests. Sometimes I think that he is my inner introverted self, materialised in dog form. As I chat with my guests, I am secretly counting the minutes until I can be alone again in my study with my writing, and my loving dog.
