Just talked to my 12 and 7 year old girls about it tonight. I carry just about everywhere and everytime I legally can. But I don't share with anyone, period. My family knows because they see me come home and take off a suit coat and there it is. My wife doesn't like it but I'd told her (as kindly as possible) that it's my right and that I intend to do it and would like for it to not be an issue between us. She accepted that. I pastor a small country church and carry there. I'm extra cautious about concealment there as I believe it could cause some folks concern. If my carrying caused a stumbling block for one of God's people I'd have to consider no longer carrying at church. When I'm in a "sensitive" spot, I go with a Keltec P3AT in pocket carry and it would be almost impossible to be discovered.
I don't even tell my close friends although I've had two close friends ask me if I've ever had CCW training. they know I like guns in general and must have figured that I would be the type to do so. I answered them truthfully but never volunteered beyond that point. If they ever ask me directly if I carry I intend to answer (with a big smile) with a question "would you ask someone what color underwear they're wearing?" I figure that'll make the point unless you have the type of friend who would ask!
There's an old saying, if you don't want to hear the answer, don't ask the questions. I wouldn't tell or volunteer so I wouldn't have to find out their reaction UNLESS it's the law, then it all boils down to your own judgement on how the relationship is. I would have to be VERY close and even them I wouldn't like it so I'd probably leave the gun in the car (something else I hate to do!)
