We go through the same ritual when visitors with children are coming over. I keep an exact count of what's unsecured.
Visitors yes. Everything up and away.
My G-kids are around guns every day. As were my kids. They do not play with them but they see them. The terrorists have an area at the end of my work bench to use their little tools on toys etc while I work on my guns. They are full aware of the dangers involved and respect them. But no, I do not leave them just laying around either.
