Why?
If she's not working .... it doesn't matter what she's doing ... whether she's "on holiday" at home ... or on holiday elsewhere .... either here or abroad. The only thing that's important is she's not working .... which is what we would expect during lockdown.
If she is elsewhere .... how do you know whether she has permission or not?
If she has gone abroad .... what does it matter to you, or us, that she's got to isolate? She's not working ... therefore it doesn't matter to us.
So, whilst we are in lockdown, it's strange that you post to tell us that you find it strange that she's on holiday. A quite unremarkable thing to tell us.
A pretty pointless piece of information about a lady who has only ever been reviewed here once.
