I find it odd that some posters think there is no practical or emotional difference in having adult children living a couple of hundred miles away and thousands of miles away.
Has anyone said that? A lot of people have backed up your point - that there is also a big difference between when family lives round the corner vs when they live 300 miles away.
For me, my family has a closer relationship with my parents (a day’s travel) than my husband’s (4 hours). A large part of that is the sort of people our respective parents are - mine are much more willing to put in the effort and meet us halfway. But also, we spend 3 weeks every year to 18 months visiting my family. That’s our absolute priority when it comes to discretionary spending. We plan it well in advance, we get the cheapest possible deals and once we get there, we have no accommodation costs. It’s expensive, but not much more than a lot of people spend on flights and hotels for a summer holiday.
And then my parents spend 3-4 weeks here, which always includes a week away somewhere in a holiday cottage. So the ‘quality’ of time they get with my kids is pretty good, although not the same if we lived round the corner. But if we lived in Australia we would not be round the corner anyway.
My in laws have been to visit us twice since we’ve been married. There is ‘no room’ for us to stay at theirs (their prerogative) and when we’ve tried to do extended stays near them in a holiday let they haven’t that been interested. So we get weekends or long weekends where we visit their house each day, but they don’t get the same one on one time or extended contact with the kids. I know if we lived round the corner it would be really different, but we don’t - DH has not lived there at any point in his adult life. For us, a couple of hundred miles has a greater impact than half a world, because of the relative abilities and determination of people to bridge the distance.
