People tend to find that they develop different personality traits when they speak different languages.
So my question to you is:
What are your languages?
And what are their personalities?
Well, I'm a native speaker spanish, you know the good thing about learning languages is that you learn new ways to think about something. Your perspective changes. When I speak in English I feel like my expressions are much simpler. Sometimes in Spanish you have to use too many words to say something. Also the change of tone when speaking is very interesting, I find it funny. I'm learning french too. Definitely it's very different from English. It's a really strange pronunciation, but it's so wonderful to learn.
