Dear lady Daniela,
First of all, I sent you this e-mail to inform you that my desk-mate is very naughty during school time, and I can't concentrate. Can you do something, please?
Second, on Thursday and Friday, I can't go to school because I leave the locality.About the lessons and the homework, I asked a class-mate to send them to me. See you at school. Thank you and have a nice day.
Affectionality, your student, Daria.
