 Two years before, I traveled to Brazil and I rented for a car. Unfortunate, I had an accident and hit another car, and I needed to stay in a hospital for at least two week. I called my parents, so I did not tell them what had happened. I knew that they will be worried about myself because I was so farther away, and that my mother would not sleep if she knew the accident. Therefore, I told them interested stories and how I was enjoying Brazil. As a result, nobody knew truth. I still think that it was the right thing to do.
