Bilingualism...

 First of all a bilingual is a person who is able to use two languages with equal or nearly equal fluency. So ,I think most of the people who are bilingual is because they are born in a country where two languages are spoken. For example, in France and in almost all European Countries they speak their language and also English, and sometimes, like Spain, they even speak three languages. In some of the regions they speak the mother tongue like Catalan, Spanish, and English. Now if I start to think how they do that maybe the answer is because they are taught since children and for that reason they learn perfectly or nearly perfectly the new language, because when you are a child your mind is more receptive and is like a sponge, you can absorb the knowledge easier than when you are an adult. And maybe the difference between those countries and South American countries for example, is the importance of teaching other languages apart from yours. I think it is a mistake because it is very important to know at least one other language apart from yours, because of the globalization and the communication with other countries. So if I'm studying English pedagogy I should do my best and who knows maybe I'll be a bilingual some day, maybe...
