I realized that I just posted but completely off topic.
So on topic, I am involved with my church's Youth Group, I lead worship in our Young Adults group, and I produce the main worship service (I only get to play in that one once a quarter or so...otherwise I'm behind the boards supervising mainly youth who help with all the technical details). I am around other people's kids nearly every day in one way or another. And I'm always carrying. Two of the youth I work with know that I carry. We are in just too many awkward positions and situations to keep the concealed part of the whole thing concealed. I've explained the situation to them and asked them to keep that info private. They know the code words I use with my family to refer to my concealed weapon. I don't know if they have said anything to their parents about it but I don't think that either would have an issue. But its a private matter (not a secret).
As far as all the other parents...I hope that the next time that I have to engage someone claiming to be Jesus who insists that we should let him sleep in the rather occupied Nursery since its his house will appreciate that I'm ready to protect them if things turn dangerous. Same goes with the office staff who regularly has large amounts of cash lying around on Monday morning.
Basically, I carry everywhere I go (except in the office...most of the time
) and I keep it concealed. If it becomes an issue with a parent, then they can volunteer to always be there to help out and protect my kids. But no one is going to protect my kids (or likely theirs) as well as I am. I consider it a large part of my responsibility there.
