, my friend, I'd like to straighten your opinion on "the second language". The second language means a language which you are using in communication besides your mother tongue as the first language.
As an Indonesian, my first language (mother tongue) is Indonesian. My second language is English. However, one of my friends, his first language is Indonesian and his second language is Arabic. He doesn't speak any English.
My point is, it's up to the people to choose their second language. Some people even only speak one language. It means they don't have any second languages.
, my friend. You can not force anybody to choose Spanish as their second language
. Don't use "must" dude !!!
Everybody is free to choose their secong languages. And most people usually learn a second language because they need it. I am learning English as my secong language because I need it. If somebody thinks that English is not important for him (of course I disagree with his idea), still it's up to him. We can not force him to learn English. To him, English is not important in his life. We can do nothing buddy. It's his life.
, supernaturally speaking, English will be being used as the second language at least for the next 2 centuries.
