I agree with Marc's point. England and Scotland and Ireland and of course Wales are all lovely contries and it has taken centuries to get them that way. Possibly that is the problem, we made it so nice that everyone wants to come here.
The UK is offcially the most crowded area of Europe and still they come. As LB states people are moving outwards and so sooner or later we will all be living at John o Groats or Lands end. Don't sneeze or someone will fall into the sea.
Also like LB we have family here and they are of course important. However, they are grown up and even our grandson will be able to drive in a couple of years and will make his own way in life. Because we live in different parts of the UK we only see each other at intervals, that is not a problem, as we enjoy the time when it comes round. I was never into the idea of living in the same street etc, being that close probably would lead to arguements, certainly in my case as I am a grumpy old sod.
So, I tend to the viewpoint that my wife and I's life is just as important and if we feel that together we wish to move then we will do so, and make the rest fit. However, to be au contraire, I would also like to be allowed to stay where I am without feeling I am unwanted, or merely a cash cow for every lunatic scheme that comes along.
I think that what we all want is a reasonable balance between having a good life, good company and the ability to enjoy it without fear. The actual location is secondary in my opinion. As my wife tells me 'home is where your bits and pieces are'.
