Greeting the babysitter

Hi! Thanks for coming.

Just to warn you, the boys have their foam dart guns out today.

They've been told they're not allowed to shoot anyone who isn't armed. (Gesture to you.)

So, if they happen to come up and say, "Hey, look at this really neat dart gun," as soon as you take it, you're toast.

Because they're not showing you, they're arming you.

Just so you know...
