Questions according to situation
If I'm on holidays I don't want to answer questions about my work... I'm not there and I'm taking a break...
If I don't have a pet, why should I have those questions?
More questions about family, friends and special events (could know that today is holiday, or sone special day for me or for the world, like Christmas or my Birthday).
Some questions could consider special news or events, like elections or wars or olimpic games, or things of the sort!
