How you come across

This year, I have noticed that a lot of children are very rude to other children and also to their parents. In the past, I think that children were better educated than now because parents are less strict than 25 years ago.

Nowadays, children aren't polite and they are also disrespectful. For example, they don't thank when they receive something, they don't show respect to older people. They are becoming egocentric.
A lot of teenagers are also disrespectful because they spit in the street, they don't wait for people before eating, they are offensive to people who are different from them.

The main reason of those bad manners is the education!!!!!
Parents have an important role in the future of their children. In fact, they have to educate well their children because if they don't, children will be rude all their life. In addition, you can't change the education of a 14-year-old child.
