Last weekend we went mountain-climbing. Even the heavy rain in the morning could not prevent us go. Setting off very early, we went along an extreme narrow road, all in high spirits. On every side of the road were green fields and some farm houses. We could hear the sound of the rain and our footsteps mixing with our laughter. At noon we reached the top of the mountain. That surprised us most there was the beauty of the scenes. After having short rest and sharing with the food we had brought, we started going down. It had rained even harder. We were wet to the skin, and we still sang and laughed happily.
