I have watched a particular family member go through the same scenario. In fact, it at one point turned into an issue where when he would show up or would get called to go certain places with certain people, he was asked to leave the gun at home. This was all at the same time that I was carrying and no one was the wiser.
The best way to get past this that I have seen is to let the issue die. Just because they know you have a CCW, they don't need to know when you do and don't have it. My relative would leave his in the car while visiting at homes, and before he knew it, they stopped asking and it stopped being an issue. He respects their right to not bring it into their homes, and they don't pester him about wearing it in public.
Just as much as majority of us are entrenched in the importance of conceal carry, there are those who are blindly stubborn as to the need or purpose of it. Everyone is entitled to their own opinion, regardless of how stupid or uninformed that opinion might be. I find that the less I make things an issue with family, the less they make it an issue with me. YMMV, but my recommendation would be to not only physically conceal it from friends and family, but mentally as well.
