Boycott - the obsession of many students in Vietnam. This is also a terrible problem that neither the school nor the parents of the students can completely solve. Those who are ostracized find going to school really stressful and scary. They were shunned by their classmates, cursed and even beaten. Often people who are ostracized easily experience many problems such as losing their confidence, in addition can also suffer from depression and lead to many bad consequences such as suicide. But completely stopping the boycott is difficult because teenagers are a very sensitive age. However, people need to express their feelings to their friends and need to listen to what their friends or children say so as not to lead to unfortunate consequences.
