Instead, I'll tell you about an exchange that just happened in my living room.
(Ethan, Aaron and Nolan are watching Transformers, which is evidently rated PG-13. At one point the main character is running from one of the evil Transformers, and is swearing up a storm, using the 's' word.)
Aaron. (looks at Nolan) We're not supposed to say that word.
Nolan. No, you're not.
(they watch a bit more)
Nolan. You know what, AJ?
Nolan. If you're running for your life away from a giant, evil alien robot, you can say that. You cuss up a storm.
Aaron. (big grin) Awesome.
Parenting is a journey, folks. :D
