Art Camp and the "password"

I just dropped my boys of at their first day camp. They will spend 5 days at the local Museum of Fine Art being artists. I'm not really worried except for the fact my kids aren't used to being in a class all day so I talked about all of the "school" issues: how to raise your hand if you have a question, to ask to go to the bathroom or get a drink of water, to be polite, etc. It was only when I was leaving that I realized we had forgotten the "password." What if somebody tries to pick them up after class who isn't supposed to? Do they know what do? Do they know who a stranger is and that sometimes acquaintances can be strangers? Do they know that a puppy doesn't make somebody safe? And, what if mom can't come to get them?

So tonight the dinner table conversation will be about the "password," that word only family is supposed to know and share when there is an emergency. How many other families do this? Are we worried about to much? Is my California background beginning to show? While we were in Europe, we never even thought this way. But back here in the States I feel I must. The news is just too full of incidents I dread to read. I don't want my kids to be in that news report.
