Oh, my wife gets it! She insisted that we should take shooting lessons (neither of us had handled a firearm before we met each other), and arm ourselves at home, in case of "uninvited guests." I brought up the fact that it is relatively easy to get a CCW permit, and she then took it upon herself to recruit the two character references for our applications!
Since then, she often points out places where a concealed firearm might be a handy thing to have. For instance, I mentioned that an abandoned section of the Pennsylvania Turnpike is now open as a 7 mile long bike trail... "Well I'm not riding on some abandoned road in the middle of nowhere without a gun!"
Our female co-workers (my wife and I work together) seem to "get it" too. I've really cringed when my wife casually brought up firarms at the office. One time my wife said something to the effect of "I'd feel safer with a gun in the office." With that, the flaming liberal Hillary Clinton fan sitting next to her spun around in her chair and exclaimed "Oh my Gosh!.........................(long pause)............... I was just saying the same thing to my husband. I know I feel much safer having a gun at home."
On another occasion, my wife asked me to open a box at work with my pocket knife. So, I pull out my Ken Onion knife (with the rainbow finish), and flick it open. Her assistant then engaged me in the following conversation:
Asst: (Sounding offended) "That's a WEAPON!"
Me: "Uhhh, No... its just a box opener."
Asst: "Its razor sharp... definately a weapon."
Me: "Well, you never know when boxes will attack."
Asst: "You can open it with one hand... that's no box opener! Say.... how much does something like that cost? I could probably keep it clipped inside my purse... just in case."
