Bilingualism.

This term is very used nowadays because many people know one or two languages besides their native language. It's very common to see people whose native language is Spanish traveling to another country for a better living and they have to learn English, for example, to communicate with the people around them. We as English Pedagogy Students are already bilingual, because we are able to communicate in two languages, English and Spanish, and some of us even in more than these languages. These days people have the necessity of speaking more languages because of the business or just because more people are having the chance of traveling around the world. There are even some countries where people speak at least two languages besides the native one. Some children learn two languages at the same time having the chance to improve their way to speak for an earlier time.
In my opinion speaking two languages is very important and quite fun, because we are able to produce the other language and always there will be some people who are not going to understand what we will be talking about and it would be like a code for us :D .
