Conversations you have when you homeschool . . .

Part of John's school work today was to watch an episode of "America" that aired on the History channel last night.  This afternoon I get the following message from Chris on my work email:
"Watching the show with John.  Apparently 1 in 4 women of the time period are prostitutes, as they show a buxom blonde and a creepy looking red-coat.  Now, your 8 year old son wants to know what a prostitute is.  Your turn!"
