Nowadays, people are all arrogant and busy. Only a few cares to say "hi" any more. When you walk at the streets or when you eat outside, you can see that less people only cares or shows kindness to others any more. Maybe its because of the increase in the population or maybe people just got tired in being polite and kind. Even in private schools where values and manners are well-practised and taught like everyday, you can see that students don't learn anything at all. You can see rude students and those that are disrespectful. Even children disrespects their parents and elders. The fact is that other people just love it when children do things that are unpleasant stuff to older people. People find this scene as entertaining and children are so innocent that they may start to think that what they are doing catches attention and we all know that children loves attention. When these children grow up, they will bring with them what they have learned while being a child and it's like an illness which keeps on getting worse.
In my opinion, I think that the idea of revolt against greater power caused this degradation of manners. This phenomena is rampant on highly developed countries and basing on that, I had the idea that the more dominant a person thinks of himself, the more disrespectful and rude a person is. I'm not saying that people should hold on to the idea that the world is developing in terms of technology, intelligence and mentality, we should focus less on manners but all I want to point out is that everything starts on what a child has seen and learned from people. Everybody should be a good example to children and teach them the proper way. I admit that most of everyone in my age are impolite and disrespectful but we are the ones who can stop the cycle by being good examples to children.
