Its perfectly normal to be honest G.
Some heavy tin drivers keep there finger in the pie and still fly GA and glide and microlight as a hobby. And others flying is a job and they make a point of keeping as far away from any airport as they can during time off
I know that, but surely even these sad and unhappy individuals who think that flying is just a job, know plenty of people at work who are passionate about flying and can answer questions like that. Plus in my experience qualified pilots, even people who fly 747s, are usually precise to the point of saying which country they're talking about - a phrase like "SE of London", or "SE England" would convince me a tiny bit more. (On the other hand, an acrimonious divorce is at-least authentic.)
Apart from that, I think your advice is spot on. I'm sure the OP's question is honest and he really wants to know, even if I'm unconvinced that he's really an airline Captain.
