Mine live 200 miles away. I’d prefer half that distance, so that visiting for a day would be possible, but I have no need for them to be round the corner. That would feel quite strange to me.
I’m often surprised at how little some families move about. We always have done. I encouraged my children to spread their wings when they went away to university, so I never expected them to live close. Also I see a lot of exhausted grandparents who are basically doing the parents’ job, taking quite a bit of responsibility for day-to-day care.. That doesn’t appeal to me, much as I love my grandchildren.
