It's very simple I begin with a question, the next one answers and ask a new question..
First person: Where do you live?
Second person: In Spain
How old are you?
Third person: 45 yrs
Do you have kids?
(Ofcourse if you can't or don't want to answer the question, you simply say something like: "sorry too personal" or "I can't answer it")
Okay I begin:
Which languages can you speak?
