But basically nowadays it seems as if you just complain a bit, because you're not allowed to see anyone etc for 1-2 years etc and then it's justified.
WW2 was almost a century ago, in the times when international travel was privilege of a very few. Everyone who made a decision to move abroad during the last couple of years, made that decision under a completely different frame of reference - it was easier (as in, cheaper and faster) for me to go and see my family abroad compared to if they lived, say, somewhere in Midlands away from big airports.
I can relate to the immigration stories from the old days- many of family branches on my own family tree relocated to the States / Canada in the early 20th century. Their goodbyes were last goodbyes, and their farewell parties were indeed a bit like funerals - it was accepted by both sides that any future contact will be through infrequent letters only, no one will see grandchildren born, no one will come and bury grandparents.
In the modern world though, I don't think that not being allowed to see anyone for 1-2 years is nothing worth mentioning. But I guess we are different here.
