Our three-year-old really likes a book called Soft Child. It is a Native American Folk Story about how the Rattlesnake got it's fangs. The moral of the story is "If you don't bother him, he won't bother you."
After a week of walking around reminding us of the moral of the story, we over heard him say to his older brother (in a very John-Wayne sounding voice), "You boddered me, so now I'm gonna bodder you."
Maybe you had to hear it to appreciate it, but Mr. Sleep-Deprived and myself had to restrain ourselves from laughing out loud.
