I would have to agree with Southafrica. There are whole new worlds that are opened up when we decide to learn a new language. The world becomes that much more closer and that much more friendlier when you can speak another language. I don't think that it changes our personalities, do I do definitely think that a new language enhances our personality, making us a more well-rounded person, culturaly respectful and open-minded. At least that how I feel about Spanish and Korean.
