I learned english without really trying to. It's just that everything I liked was only tld to english, so it just kinda happened while I was listening to music, watching movies, playing VNs and such. Same with spanish, though my spanish sucks. My native language is portuguese, and I'm currently learning jp.
Language, to me, is nothing but a way to communicate with other humans and enjoy myself, since it's needed for any sort of entertainment. I don't have any special attachment to any language, and in fact, I think it would be better if everyone spoke the same language, since I don't care much about the cultural aspect of things.
