I recently found out that my friends mom, who is from Spain, actually knows English but she was too afraid to speak it around fluent speakers. I feel like I can relate because for a while I was embarrassed to speak any Spanish because I did not know how to pronounce certain words and I could not roll the "R". :)
I would like to share this article I recently stumbled upon about how to overcome the fear of speaking a new language. In the article there are some great tips to try if you or someone you know is afraid to speak a new language to someone who is fluent.
