Ithink that this profession is difficult and very difficult. if i were a teacher, i would first of all find an approach to students and become their school friend. for this, sometimes instead of lessons i would go with them to the theater or to the cinema, as well that the weather was good, i would have had a lesson outside. at the lessons i would not swear at them if they did not understand the topic, i would stay with the student who did not understand after the lessons and explained again. probably, in my lessons there would be a place and jokes, humor (of course, within reasonable limits). i would like to be a fair and strict teacher. a good estimate must really earn. but if the child deserved the top five, i would put it with pleasure! also, if i were a teacher, i treated all children equally and i wouldn’t have pupils whom i respect very much and give good grades because they go to a letter. i would like to say about parents' meetings. there i, as a teacher, would first of all try to inform moms and dads in the good features and deeds of their children. in turn, they could also tell about the positive aspects of their child, which should be developed. in general, i would like to be a teacher who loves his work and love children
