If I'm there as a social guest I would leave entirely. I have real credible threats against my self and family and there's nothing going on at your place which would justify my letting down my guard to those threats.
Please understand that this is not meant to be personal to you in any way, nor is it unique to firearms. I would no sooner leave my cell phone in the car, either, because my child or elderly parents might have an emergency.
My need to have the item is so great that I would be willing to cause tension in our friendship to keep it. I don't make the decision lightly, and I'd rather not have to make it at all, but if I'm forced into the corner have have to make it, I choose the item. Your gun-free house can't protect me from the very real gang members my ex-wife riled up. Your gun-free house can't protect me from the rabid wild dogs I've had to shoot in the past (which are the reason I started carrying in the first place).
If I'm there as a contractor, I would put it in my car and look for an opportunity to retrieve it while you weren't paying attention. I need the job, so I'll make nice with the client, but I also need to be ready.
I have a hard time conveying to people how nieve that statement is. I didn't ask for my ex to turn bat-**** crazy and stir up some gang members. Chances are I didn't specifically request to be sent to you house, either. I just take whatever jobs I'm handed, employers tend to like that quality.
From where I'm coming from, I have bills to pay just like everyone else. I have to have a job, and carpentry is what I'm trained in. It takes to much time and money to completely re-train to another profession just to roll the dice and see if that employer/client allows firearms. If they don't, then folks like yourself would expect me to take a few more years and another $10,000 to re-train yet again. I end up in an endless cycle of training, never actually having a career, all because I want nothing more than to exorsize a specifically enumerated constitutionally protected right. Also, there are credible threats I need to be ready for. I feel, and this is just how I view my situation, that I'm in a survival scenario. I have to avoid detection by the employer and client while remaining ready for the ex-wife's angry gang boyfriend.
The way I see it, non of this has anything to do with respect in any way. It has nothing to do with respecting you or my employer. Braking the rules has nothing to do with disrespect, either. To me, the entire topic of respect is completely besides the point.
To me, it's about survival.
