I also have close family in France and Germany. I know what this is like, much as you are trying to make out I don't and that you are suffering more.
I still think we should have closed our borders to tourists - to & from, and any travel not for essential supply or essential business purposes.
The thing is, if UK citizens work abroad temporarily - as Gastarbeiter, basically - then again, the costs of doing so need to be factored in.
There are always risks to making such choices. If you're prepared to take the profit, you must also be prepared to take the losses.
I hope I will see my mother (in Australia) and my last remaining aunt (in Germany) in person alive. But I also think of all the deaths from this disease, and all those others who won't see family or friends alive.
Because, no this isn't all about me. This pandemic has shown just how we're all - strangers - interconnected. That there is such a thing as society, not just individuals & families, and our actions taken can have consequences for complete strangers.
