You have a conversation like this:
Friend: I heard a fighter flying over my house last night. It was particularly low.
airforcewife: Did you?
Friend: Yes, and that's very unusual here.
airforcewife: Well, I don't know why it would be. You have [rattles off names of several Air Force Bases] around you. Plus there's [names of Navy Bases]. And don't forget all the civilian bases in your area, too.
Friend: Civilian bases? You mean... airports?
airforcewife: Um. Yes. Airports. Sometimes I get stuck in a mindset, you know.
Friend: Yes. I've noticed.
