I’ve been in situations where someone on the table asks a question nobody knows the answer to and the conversation just dies then and there. For example, someone might say: “…and then I saw wallaby from my hotel window, so I started wondering if they would eat those nice flowers I saw the day before”. Well, nobody on the table knows what wallabies eat, so nobody said anything and the conversation just died.
Instead of anyone saying “let me google that”, there’s a long silence and then someone just takes the conversation in a completely different direction by saying something like: “oh, BTW I’ve been thinking of getting a new car and that’s when…”
