What is your opinion about indonesian teenageis nowodays

In this era of modernization many teenagers follow the flow of time without thinking selectively in filtering out foreign cultures. Indonesia which was famous for its manners even because of the modernization of many who act rash, drugs, brawl that often happens among schoolgirls, clothes that are not ready to use instead in use for example a very short skirt woman. Indonesia has changed. But do not blame the incoming foreign culture but the people who are the ones who must always maintain the culture of Indonesian courtesy. I think this handling should start from myself in order to be an example and an example to the crowd. . May we Indonesians become virtuous human beings.
