You know you've done something right as a parent when you open the door to the room where your children are happily playing and say, "Okay, it's time to clean up!" and their response is, "Yeah!!" And they get busy cleaning up.* Hmmm...did they hear me right?
*Although my kids are good about cleaning up when I tell them, this cheering has only happened once. I felt I needed to disclose this tiny bit of information before anyone began to think that I have perfect children!
