Great story about your Serbian guest ... and a great service, introducing foreign students to *conservative* Americans!
The next year, we had two girls for the full school year from Eastern Europe. Their area coordinator was a RAVING liberal, when we went to her house for a host family gathering, there were Rat posters ALL over the yard. Imagine that woman's face, four months later, when we showed her pictures of our girls from the county fair, and a couple of them were from the BB pistol target shooting gallery! Since meat was merely a flavoring in their home countries, they enthusiastically told the coordinator about the meal at the Chinese restaurant where we ate six different species of animals!
I really loved tweaking that woman!
