So in the driveway, I take my kids aside before we go out and I hear myself saying, "Listen: this is going to be really fun if you remember one thing: we are dressed liked superheroes. We are not really superheroes. Don't try to do anything dangerous like run in front of cars or put a forcefield in front of a truck to protect yourself, OK? It won't work. This is pretend."
The crazy thing is that they understood exactly what I was saying.
We won first prize at church, btw. My wife had a costume, too. She slaved over them, and I was pretty much blown away over how much she's willing to put up with to be in a family full of superhero wannabes.
And no, you cannot see my kids faces. Those are the rules.
