My job
Hi, I am a teacher, I work in a primary school, and I love my job and my students. Today is the first day of the new term. I am very happy to see my children. They are taller and more beautiful than last term. We are busy today.
They came back to school and cleaned the classroom, took their new books, and listened to the new term's rules. I am busy for with clearning the office and preparing the new lessons. I hope we have a good time this new term.
