My unusual teacher)0))

My teacher of Russian language has come up with a very interesting method ... For the reason that my class-mates does not study and we are stupid (with love) she said that if we find mistakes in the texts or some announces she will give a high ball. I'll explain .. I'm walking around the city , for example, I'm looking at a big beautiful sign and it's written with mistake, I will take pictures of it and I will show to my teacher explaining where the mistake is made and how it should be written and the teacher will give me me the highest mark))))) I found an error in the book "Love lives three years" by Frederick Begbeder )))) I think it is mistake of translation )))
