I am not sure about my future plans. I think that after finishing school I will get higher education or I will go to some technical school. I’m going to study and to work simultaneously. My family lives in Mariupol (свой город) that’s why I think that I will spend my life in my native city. I don’t know what to become. I will choose my profession from financial point of view and for interest, too. I am not afraid of hard work if it brings me enough money.

I wish I would meet a lot of interesting people in future because to associate with original people is a great pleasure. I hope my future life will be various and full of interesting situations. I want to travel in future when I’ll be able to pay for it by myself. I wish I would have my own house and live there with my husband and children. I think that I will go on to associate with my old friends because old faithful friend is the best from two new friends, it’s over clear for everyone. But no one can say for sure what his life will be
