It is exaggeration Varian. Of course you will miss your beloved grandchildren but you will easily be able to visit them (health allowing) and Austria is such a beautiful place to live in and to visit.
One of my children is a doctor, married to another doctor. They are considering emigrating to Australia, it is a lot further away than Austria. But I do not consider my life, or theirs, to be being smashed to pieces. Of course I would prefer them not to go, and will miss them in a way that I find too difficult to describe, as we have always had such a lot to do with these beloved children, but if they will have a better life, then so be it. It’s nothing to do with Brexit, it’s to do with the way doctors are undervalued in our NHS, and that Australia values the skills they offer and rewards them appropriately, unlike GB. I still hope they will not go, but we’ll have to wait to see.
Families are parted by emigration and always have been, it’s nothing to do with Brexit.
