This is not a question but rather a link to a very recent article on living in Paris and studying at the Sorbonne. The student is actually a professor at the University of Texas at Austin, Gregory Curtis. There are some interesting practical tidbits about getting a student visa, but mostly the article is about his experiences as he lives in Paris and studies "French Language and Civilization." Here is the link for anyone who might be interested: http://alcalde.texasexes.org/2014/08/excuse-my-french/. The article is from the Alcalde which is the alumni magazine for Texas Exes.
It is all informative and entertaining, but I was particularly struck by his comments about living in Paris for six months. I think they could be applicable to anyone who would like to live anywhere in Europe for an extended period of time. They come in the next to last paragraph of the article.
