I know Mumsnet is really good at this.
Working with a couple of people at the moment who quiz in a way that FEELS a bit grilling and personal and uncomfortable really - although I don't think it's meant that way.
'Have you not got a husband?'
'Why do you not work?'
The way they are phrased feels critical.
How can you indicate questions are not welcome without being, well, rude I suppose?
