You asked for it, so here it is! Palin speaks about her experience speaking to 2nd graders (warning: you may not want to watch past her remarks, as Buchanan blathers on and on and on...fair warning!)
Needless to say, when speaking to schoolchildren, it is important to give accurate information. It is also perfectly acceptable to say, "I don't know. Let's find out." Adults don't have to have all the answers, but do need to know where to find those answers. And when speaking to adults and relaying the questions put to you by children, it is equally important to be accurate in your answers, especially when you don't fully comprehend the office to which you aspire.
For you, K., for your great idea in the last post's comments!
