Cultural Awareness

How many things we teach when we teach a language....Teaching a foreign language is a great opportunity for students to know about other people´s cultures and to compare and contrast it to their own.In that way they will be more open minded and ready to accept differences.
Which issues do you think we can discuss with students after watching this video? It comes to my mind our typical drink, "mate". I would also ask them to find out information about the "Tea" party in England. Other ideas?
