Who are they and how they look? In the streets, in parks, cafes, on discos, everywhere you can see young people standing together and talking about something with great interest. What are they talking about? They talk about studying, music, clothes and about money, which will finish soon. But in spite of the problem they are never sad. At the same time students walk in town, go to cafes, discos and concerts.
Students become friends very fast and forever. Perhaps later when they meet they'll talk about how they are glad to see each other how they were missing and call each other brother, thought they were studying in different groups and saw each other only during the entrance exams. But this will be in future.
And now there are some different types of students. One part does nothing but study. Others have time for studying and for things they love to do. Someone likes going in for sport, some are fond of playing computer games, other like singing or dancing and so on. And there are some students who don't want to study and want to graduate the university with good and excellent marks.
Students wear everything that is comfortable to them. They listen to different types of music. Pop, rock, rap these are only few types they listen to. And all students like sleeping. So they are very different.
