An extremely liberal, very old friend of ours visited China a couple of years ago. She sent us emails describing the air pollution/water quality and ended them telling us to thank God for our being able to live in America. It was evidently quite the eye-opening experience for her.
Funny you should mention that......my friend is also quite liberal, thinks socialized medicine would be great, believes that humans are causing global warming, etc., etc., etc. Her husband is not liberal, however, so it will be fun to hear how the vacation goes from both of their points of view. They are going in July.
