Not family, not friends, no one
Aside from you folks, of course. Concealed means concealed, hidden, without a trace. Personally, I feel it's no one's business but my own. It's not a game, nor do I feel the need to be an extrovert about it.
If the OP feels the need to explain his actions to all he meets, so be it. I carry because I've been a helpless victim in 2 robberies, and don't plan on reprising that role. I like guns, and feel totally comfortable carrying them after quite a few years of doing so.
