What has learning a language given you?

The central image in this poster is a screenshot of the wallwisher linked here, which asked the questions: "What has learning a language given you? What do you love about language?"

If you love languages please add to the wall by simply clicking in an empty space on it and expressing what languages have given you. You can even link to video, images or audio in your comment.

The text below the image seemed a good idea at the time but basically arose from the presumption that so many people still make (I still hear it at parent teacher interviews); that is, we don't need to learn another language as everyone else speaks English. I am fairly sure that I am not alone in my opinion that this belief is not quite on the mark, kind of like the views of those who dismissed Galileo's views back in the 17th Century.
