Just that really. I grew up in the countryside, but have lived in London for about twenty years, and love it. Loads of our friends are moving to the country, funnily enough often to the area where I grew up. They sometimes invite us for weekends which is obviously lovely and generous but I can't help getting a little bit annoyed when they act as though they are giving us a glimpse into an idyllic lifestyle we have mistakenly foregone and/or start slagging off London, including what a terrible place it is to bring up children. The latter happens quite often. It's also quite difficult to persuade the same people to visit us in town once they have moved out. Why is that?
