Everyone had some accidents at least once in his life, and I am not an exception.  It happened to me 5 years ago, I was 10 years old at that moment. Just as summer began, I went to the summer camp where I always spent my holidays.  I met my friends there again and we had fun together, we swam in the river, sunbathed, played football and took part in different competitions. One day, while I was sitting with my friends on the bench, we heard a girl crying. She was younger than we were and she looked so sad. I suggested my friends going there and asking the girl what had happened to her. She told us that her kitten had climbed  the tree to catch a bird. However, the bird wasn't caught because it had flown away. And the kitten could not get down to the ground and cried. 
My friends just listened to the story and decided to go away, but I felt for the girl and her unlucky kitten. Hoping that I would be luckier, I decided to climb up the tree and save the kitten. It had been the first time I climbed such a high tree, by the way. So as I was very close to the kitten I took him with my hand. Suddenly the branch where I was sitting cracked and broke and I fell down to the ground. 
As a result, I broke my hand and was taken to a local hospital. But I wasn't dissapointed  at all, because the kitten was saved.
