Actually…’are you married’ is a question I never feel comfortable asking straight away. It sort of implies you are finding out if they are available, which is no good to me as I’m not lol. I normally check their hand and make some sort of reference to it a bit later.
As for the 20 questions lol…I don’t ask all that many – I usually just go slowly, askig a question now and then and letting the convo drift round to the rest.
