I went hiking to a mountain with my friend last summer. It was a good trip in the beginning and something unexpected happened halfway. One of my friends suddenly felt a terrible pain in his stomach and he couldn’t move any far. Nobody knew how to deal it. One girl tried to call her mum over her mobile phone, but there is no signal in the mountain area. Lucky we had brought a tent with us. We put it up and let him to rest in it. After taken some pills, he drank some water and ate some food. After a while, I felt much better and we walked on. We all enjoyed us on the top of the mountain.
