It's taken me several years to realise that when someone asks brightly: "How's the flying going?", it's a bit like asking you how you are. That is, they don't really want a blow by blow account of your difficulties in landing in that strong crosswind and how you got lost in poor vis on the way home with low fuel etc etc etc, any more than they want to know about your aches and pains and the result of the latest hospital test. Both are polite questions, to demonstrate that they're interested, that's all. "Just fine" is an appropriate answer to both.
However, if they THEN ask: "What are you flying now?"; "Have you bought an aircraft yet"; "Have you flown to..."; "Have you done the ... course?"...... well, then you're at liberty to drone on for the next two hours - because they're either genuinely interested, or stupid enough to pretend to be.
