Last Sunday I went to the cinema and saw a film_that__tells a story of an American high school girl _who__woke up one day to find that her father ,_whom__she has never seen,is a king.Before she knew she was a princess,she was the most unpopular girl in school,the kind of girl__whom_few people would give a second look.
Things were not the same when it became known that she was a princess.she no longer had peace at the school__where_she studied .she was frightened by these _who__only wanted to make a fool of her or use her.It turned out that the only people __who_she could depend were these__that_had always stood by her in the days__when_she was unpopular.There were many moments _when__she wanted to run away from this life ,but in the end she was encouraged by her father's letter and was able to lead the life of a real princesss.
