Good post Daphne. Our DS and DIL apparently settled here with house and good jobs decided to go to OZ, where they immediately had resident status.
We were naturally upset, but cheerfully wished them well.
Like other posters, behind the scenes were many tears. We were fortunate to be able to visit, Skype and phone.
Their life was living the dream, beautiful apartment overlooking the Pacific, great weather, good leisure facilities etc.
But they returned after 2 years, they missed the families: the happy and sad family events that they could not join in with. It does not mean that they will not go elsewhere or even back to Oz in the future, but it is their future and we must respect it.
