My favourite film
I really love to watch films. We often go to the movies with our parents or friends. Usually I like historical films or cartoons. Mom loves movies about love, and dad loves movies about superheroes. Recently my whole family has watched the movie "Hachiko". This is a story about true friendship between a man and a dog, based on real events. One day a man named Parker found а puppy at a train station. The puppy became a kind and friendly and loved Parker most of all. They have spent a lot of time together. The dog went with his friend to the station when he went to the university to lesson. In the evening he met the train in which Parker returned home. It was their tradition, this continued for a long time, until the bad situation happened. Parker died at the lecture from a heart attack. Hachiko still came to meet him, but no one came. From this moment the saddest part of the story begins. Parker's family tried to take the dog to their house, but he left at the station, where he continued to wait for his friend. He waited for him for ten years and died in this place, as an example of endless love.
