Bullying has become a major problem, especially in our modern society where children are spending a significant amount of their time online. That can be the cause of higher risks of being bullied.
My opinion on bullying is deeply negative. I wish there would be an effective way to prevent people from bullying others. They aren’t any different from them, generally speaking. After all, we all are human beings who live under the same sky.
People must be given more speeches on a sense of morality, on how bullying can not be tolerated included. Moreover, bullies must be punished for their doings so that they don’t repeat the mistakes made.
I hope such social issue would be solved in the nearest future and numbers of those who are being bullied would drop.

Ihave not decided what i shall do when i become an adult. choice of vocation is not a simple matter, because the interesting professions in the world very much. perhaps i'll be the doctor and will be able to overcome the insidious disease. or, piercing the space, visit other worlds. maybe i'll explore the mysterious corners of our planet, or engaged in the cultivation of bread. and maybe i'll go to the scientists and find a new energy source, or just invent a kitchen robot that will instead of my mother to cook the lunch and wash the dishes. but i perfectly understand that the knowledge gained in school will help me in the future, when i get to work for the benefit of society. я пока не решил, чем буду заниматься, когда стану взрослым. выбор призвания ‒ непростое дело, ведь интересных профессий на свете много. возможно, я стану врачом и смогу побороть самые коварные заболевания. или, пронзив космическое пространство, побываю в других мирах. а может быть, буду изучать таинственные уголки нашей планеты, или займусь выращиванием хлеба. а может, пойду в ученые и найду новый источник энергии, или просто изобрету кухонного робота, который будет вместо мамы готовить обед и мыть посуду. но я отлично понимаю, что знания, полученные в школе, обязательно мне в будущем, когда я стану трудиться на пользу обществу.
