Sure was lucky you didn’t work on any of those classified projects - <wink>
I never know what to say about my residence. Even now, I own a house, but I don't consider it my home, at least not all the time. Have a specific "residence" presumes that there's one set of coordinates on earth that is canonical for each human, but many people don't live this way.
Is there a definition that cuts through this?
You wouldn’t make a good candidate for a national security job, not that it sounds like you want to be. Investigators would want to know who you’d been associating with at all those different places, and tracking it all down would take a long time ( the wait for the investigation can be years, the period during which you’d be unhireable for the job you were going after.)
But I take your point of course. :-)
