Unfortunately, quite a few young people in different countries are inclined to behave badly either in classes or at home. Obviously, there can be a lot of reasons for that. From my perspective, the two factors might be the most significant. Firstly, lack of parenting and adults’ attention is a key reason for kids' abnormal behaviour. Secondly, excessive playing of computer games may well take its toll on students. I believe, first and foremost, parents should be involved in tackling that issue. It is paramount to channel children’s energy having found what interests might they have and giving them the opportunity to be involved in a process they are passionate about instead of wasting their energy on negative things. These thoughts will be discussed in the essay below.
