My Twin Sister?

I guess you didn't know I had a twin sister.
It's so funny all the kids at school will call me by her name or her by my name. They insist that we look alike. When her sister got laid off she told the kids it was because she was bad to the kids. All the kids pointed at me and said I told them, but the truth came out and everyone got a laugh out of it. I told her she had better do the right things because I don't want to get blamed for her bad mistakes (I'm always good so she don't have to worry).ha ha
