I do agree with Patricia Ryan keeping a language from dying out preserves the culture built by the people who use that language. I also think people should not require another person to learn their language but to encourage them in a not arrogant way. I think knowing more than one language is a good thing because it can be a gateway to meet more people and learn about another culture. Also learning another language comes in handy if your in that country or a restaurant or something has the option of using that language.
