I want to lean Italian because it can save lives and prevent espionage plots from being uncovered:
If you haven’t seen “Inglourious Basterds” yet, watch it! It is one of the best films of the last years. It is worth to watch it for the performance of Christoph Waltz alone, and then one more time just for the film music.
On the subject of this post, I actually had Italian at school for one semester and therefore know the basics, but I would love to learn it again and much more in-depth. Maybe I will move to Italy next.
