You mention radio stations. I started doing radio when I was 14, about 70 years ago. Radio was better then than it is today. I regret that and I find it unfortunate to see radio stations allowing, for example, so-called comedians swearing and saying terrible things on the air. Kids have their headsets these days and they hear those things. I feel the same way about the stories on television or video games. There are good video games, just like there are good things on the Internet.
The other day, a young girl told me that she had learned five languages, including Russian. I asked her where she had learned Russian. She said that she had learned it on the Internet. She had even learned how to pronounce it. You cannot tell kids that you forbid them to do something. You have to say "suggest", because the moment you forbid children to do something, they will go and do it. But if you make a suggestion, you are engaging them and getting them on your side. Perhaps you are getting somewhere with them.
I always come back to the identity card I mentioned. I went to congratulate the students after the three months. Well, if this big fifteen-year-old guy did not get up and use an expression that I have not heard for a long time. He said that he was the kind of guy who could easily freak out. He meant that he had a terrible attitude and got angry for any little reason. He went on to say that, thanks to some people, whom he mentioned by name, he had managed to improve and that he really wanted to thank them. Some girls were so surprised that they went over to give him a kiss. It was not staged, it had not been prepared. But the improvement had still been recognized in an official way.
