Some time ago I saw an article about how people change their personalities when they speak another language, and I thoght about that when I was writing the post. I thought that may be is a part of movin your face differently. That may be we unlock something that's hidden in our own bodies when we start movien different muscles. It was a very scientific article, so I guess you're not wrong when you talk about being a different person on your Swedish learning.
That "Borrowing personality" part is kind of scary, haha... But at the end we always tend to act pretty much like the people we spend more time with, so I guess that also might be true.. jeje
