My fit and healthy parents in their mid-70s have been in Portugal for the last four weeks and are planning to stay another two. They are having a lovely time! And there are no confirmed Coronavirus cases in the area where they are staying. They would be able to change their flights and stay longer, and get an Airbnb. As I don’t think we would see much of them over the next couple of months anyway as we will stay clear as we work and travel into London, I am trying to persuade them to stay put where they are. They seem keen to come home, but I have warned them they will need to socially keep themselves to themselves once they get back (which they would probably do in Portugal too), as I am worried purely because of their age and the fact that the virus is more serious the older you are. AIBU?
