Last Saturday, my friends and me went to climb the West Mountain. While climb, we enjoyed the sunny weather. We were very delighted reach the top without much time or effort. Therefore, we found it more difficult to go down. So we went slowly but helped each other when necessary. Though I took care a lot, unfortunate, I slipped and hurt my leg badly. As the result, I could hardly stand up. One of my friend came to me immediately and carried me on the back till we reached for the foot of the mountain. I am very thankful of having such good friends.
