In winter 2004/2005 we went to Zakopane for a class trip. It was very cold and there was a lot of snow. We were staying in a hostel near the mountains. In the evening we (I and my 3 friends) decided to go to the mountains for few hours. We did not tell anybody about it. We left the hostel and walked for some time. It was getting dark and we wanted to return to hostel. But one of my friends started running and behaving stupidly. He was running and he did not see the hole in the ground. He fell. We ran to him and we tried to help him. We were shouting. A man came and helped us. He carried my friend to the hostel. The friend did not look well. His leg was twisted. The ambulance came and the doctor helped him. The teacher was very angry that we left the hostel. We could not leave the hostel - we did not go anywhere with the class and the teacher. It was very boring. We were angry with the friend who caused it but we were also angry with ourselves. We will not do anything like this in the future.
