Your approach sounds sensible to me.
In the long run, I have found it wise only to offered advice when asked for it, so I start out by telling new parents, that I shall be very willing to hear their concerns, but will only give advice if I am asked for it.
What made you fall in love with comedy?
What do you miss from back in the day?
What sort of family would you not want to marry into?
"Old fashioned" expressions that young people have never heard.

So, I have learnt a lot, thank you all.
