My best friend is Olga. We study in the same class. She is a very talkative companion. I like to talk to her. We have much interests about sport. Volleyball, skiing, ice skating and rollers don't allow us to miss. It's fun! But we have a different favorite subject in school. I like to learn russian, literature, but she likes maths and phisics. But it's good because we can give some advices about solving homework each other thus we can get good marks for tests. We will never leave each other in the lurch
