I'd like to continue with our discussion of idioms. With this in mind, I have two tasks for you (for those that have time).
1. Find an english idiom (perhaps one that is new to you); try to find out what it means, and be prepared to explain it to everyone.
2. Read the following text by Richard Lederer (available at this link): http://www.usingenglish.com/weblog/archives/000429.html
I find the text to be very funny. It light-heartedly discusses the weird contradictions of the English language. If you have time to read the text beforehand, do so. Make a note of anything you have questions about. Together, we will then go through the article to understand its nuances.
I will also bring several idioms to share (I noticed several when I was watching an American movie the other day). Feel free to bring any questions you have about idioms, or even a Spanish idiom or two (provided, of course, you can translate and explain it in English)!
