I say Mandarin Chinese would be much more beneficial to learn, since there are about 955 million native speakers in the world. Japanese and Korean wouldn't be silly languages to learn in school either, since there is a lot of business to be made. Personally I would go for Russian, so that I would be able to say more than здравствуйте and спасибо when talking to my eastern neighbors.
When I was young, there was a god with infinite power protecting me. Is there anyone else who felt that way? And was sure about it? but the first time I fell in love, I was thrown down - or maybe I broke free - and I bade farewell to God and became human. Now I don't have God's protection, and I walk on the ground without wings, but I don't regret this hardship. I want to live as a person. -Arina Tanemura
