In this society, I believe that teenagers nowadays are mostly well behaved. However, there are also a handful of them who are not. This not well behaved teenagers often not only misbehave when they are at home, they even misbehave in public. From what I have see, the most common one is them using vulgarities in public, as and when they like. Not only they are degrading them self, people around them will also feel annoyed and insulted.

I believe what causes this is due to a lack of moral education. However the school has been teaching us moral education ever since we attended primary school. In home, our parents also teaches us to be well behaved and ban us from using vulgarities. So what exactly went wrong? It may be cause by peer influence. When one sees their peer being rude, they will imitate and slowly they will catch the bad habits.

People around those rude teenagers may actually speak to them and not scold them about their disrespectful way to other people. I believe if things were to be talk in a calm manner and not by scolding them, rude teenagers will gradually change their behavior and be a better person.
