Notavirusalso. Sorry but you seem not to have read the whole thread.
My first post was :-
"Don't worry too much about knowing the correct answers. The person questioning you does not know the answer either so you can say anything you choose."
That was intended to inform interviewees that they did not have to get worried that they may not know every intimate detail of their spouse's life history.
It was this simple remark, intended to be helpful, which was criticised. I accept that I should have just ignored that 'unhelpful comment' on my post
