When I was planning to go to Paris, I pulled out my college French books and brushed up on my vocabulary. I went on a tour and met a Korean woman who was about my age and told me that she studied French for six weeks before her trip. She figured that most French people don't speak Korean. I was really impressed. Her English was pretty good for someone who had never lived in an English speaking country. Her French was even better. You could tell that she really made an effort to fit in to the French culture.
When I was in Paris, most French people were very nice and patient with my mediocre French. Most people spoke English, but that is because they worked in the travel industry. I have nothing but positive things to say about Paris except that the Louvre was too crowded near the Mona Lisa.
