If I tell about my characteristics my skills and character, I am not serious. I am cheerful and energetic girl. I do not get upset and depressed because of small unpleasent events. If they hurt me, I feel sad inside for a while, but immidiately I deal with that person again as if nothing had happened.
It's against my character to be sad, hold a grudge, cry and be depressed. Another thing worth mentioning is that I do not realy like doing housework, or rather, I do’nt do any housework.
Even in my own house. I do’nt do any housework. My father doesn’t ask my mother to do the housework for our daughter, because she says; “It’s enough if she studies well” I do laundry for my sister. I am almost always alone in my room. If there is a person in my room besides me, I can not live with him. Because the person who lived in the same room with me can stay the night only if he agrees to my terms. Because of this character of mine, my own sister also kicked me out of my living room. It’s true, maube I am selfish, cheerful, positive, self-confident girl who loves herself, but I can quickly adopt to a new place. I will sacrifice everything for my goal. I do not want to brag, I can quickly adopt to a new family and foreign school. Because I am a positive and very curious person. I am very interested in the possibilities of the school environment in other countries. As soon as I succesfully pass this international olympiad, I want to compare my family’s living conditions to my future American one.
I think I have these qualities that help me to be a flex exchange student.
