I've always wanted to be as multi-lingual as possible so I guess it wouldn't matter as long as I learned other languages at an early age as well. English is a good business language as a starting point and translators are very commonly available with it as the middle language but out of pure preference I'd pick a non-sexist based language. English isn't too bad for that simply because it's a junk language of so many other languages but it still has it's sexist possessives and I definitely wouldn't go for what are known as the Romance languages.
i love my first language ...(italian)
but i would like to speak english to understand all the song that i like(it's a stupid thing, i know)...every time i have to translate in my head all the lyrics .
what makes it somewhat complicated is all the slang you guys use.
