I look forward to, and enjoy, Christmas. That said, whether a middle-aged man stalking John Lewis for a present for the self same woman (after 43 years what's left to buy?), or a young mother weighed down by clinging children and shopping bags, the season has its downside - not least when the sky is piddling down. Thank god for the Dog & Duck. My first visit was to the Post Office, to mail our greetings cards. It's a dying custom, literally.
