When gransnet was young, I was keen to recruit, and told a group I was meeting with - 9 people, most the right age, mixed sexes, some I knew had grandchildren, some I didn't know. I described the cameraderie, the different opinions on religion, politics, scientific advances, the word games, the chaffing, the chats with like-minded people, the meetups in person, and, in passing, the chat about grandchildren.
One bloke said "I don't think I want to join to hear all about people's grandchildren".
Close of subject. The image of grannies boring for Britain is hard to overcome.
