Ideas: Japanese Mandarin Spanish Portuguese Italian German and maybe French
I need them all in order and I need what looks good (ie OH, that shows he's smart too, but also fun and interesting, usefulness is not a problem for me.

I feel like how ignorant can you be....do you agree? I've called anyone a wanna be american or englishmen for speak or wanting to learn to speak english...

I am debating on taking Russian, French or Portuguese as a minor for college. I am already bilingual in Spanish so I don't need to take a class for that.

I can already speak 4 languages and i want to learn one more. I really want to learn either russian or portuguese. Portuguese is a really beautiful language and brazil and portugal are two very beautiful countries with lively cultures. I also know that portuguese would be a lot easier than russian. Russia is not as beautiful a country, but the russian culture is still fascinating as well as russian history and literature. Can you help me decide which language I should choose.
