While living in both France and Canada, I have often helped my fellow classmates with their English (in France) or their French (in Canada).
As a scientist, I love a good challenge, but don't let that discourage you! I also enjoy having a good time! The more we can laugh, regardless of how challenging a lesson seems, the more you will learn! Over the years I've found this to be true with most of my students!
I love learning languages too. I am fluent in Spanish and am currently learning German, Norwegian, and ASL. Languages are in my opinion, more than just a means of communication, but they're also a part of a culture. Languages are a way of viewing, understanding, and thinking about the world around us!
