Why not "are you all alone?"
That should work. However, I think the problem with it might be it being taken as "you all" instead of "all alone". So, "are you all alone" = er I alene? instead of Er du helt alene?
Yeah probably I can see that point. I also wrote it 8 months ago, so it may be changed since.
mhmm, it has !
Sounds like something a potential killer would ask on the phone.
Jeg vil tage, jeg vil tage, jeg vil tage...
Det ekstra skridt
"completely alone" other than the one asking the question
What about "quite alone"?
They should accept 'Are you quite alone?' because quite in this context means entirely alone - not alone-ish!
