Thanks for all the many answers....I completely overlooked the fact of telling them to never mention it in public. I also overlooked the fact of having a plan in case something bad does happen while carrying. Those are great pieces of advice and I am dumbfounded as to why I didn't think of that. I guess I never thought of not telling them I was going to be carrying. I just figured they would eventually see me taking it off or carrying around the house somehow. They seem me online researching them, reading this forum, etc. I wanted to put a good spin on it as opposed to "this is for protection from bad guys" and leave them with some fear of the bad guys are coming to get us. They think nothing of my shotguns, rifles, muzzle loaders and going hunting. I want them to feel the same way about a handgun.
I was thinking of saying something positive along the lines of: "In school you will study about our founding fathers and the constitution. The constitution grants every U.S. citizen many rights and freedoms (freedom of speech, religion, etc.). One of the most important is the right to keep and bear arms...some people choose to exercise that right and others do not. Dad went and got special training that allows me to carry a gun concealed (although open-carry is legal in MI, it appears that most LEOs either do not know this or choose to hassle you about it)....when people exercise their right to carry guns, it makes them feel good knowing society will be safer and reminds them of how important our constitution is along with all our rights....My training allows me to carry my gun concealed or "hidden" and you must never say anything to anyone."
That may be too over the top, but I just thought a positive spin of mentioning the constitution, our rights, getting special training, etc. might help them understand the importance of handguns and concealed carry.
If anyone has other advice, please keep posting.
