Two Week Accent

I was talking to a cute teen girl at the library the other day. She was talking to me in a British accent. She has never stepped a foot in England in her life. I asked her why she was speaking in a British accent. She said that she had been speaking in the accent for a week and that she had a week to go. She was convinced that if she spoke in the British accent for two weeks straight it would stick.

I know that people say that you can develop a habit in two weeks but I do not believe you can develop an accent in two weeks. I did not want to burst this girl's bubble since she was working SO hard at it so I just smiled and said, "Wow, you're really good." I'll see her this week and we'll see if it "stuck." I'm more than doubtful.
