Once upon a time there was a huge and multicultural world… There were people from everywhere that you could imagine and the most important thing, they were all happy. They were all kind, hard-working and multilingual people. They worked and lived in peace. They were respectful with each other and they tried to help each other. The baker made the bread for everybody and the teacher taught all the students. There were never problems or disrespectful times. They were all respectful with each other and they thought about the future as something very important. They wanted to live in peace and happily. Their only concern was the future of the new generations. They wanted to give them an even better future. They knew that they had to learn from each other, respect each other and think about progress.
That was a perfect world. Full stop.
