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 house. We could hear the sound of the rain and our footsteps mixing with our laughter. At noon we reached top of the mountain. That surprised us most was the beautiful scenery there. After having a short rest and sharing the food we had brought it, we started going down. It rained even harder. We are wet to the skin, and we still sang and laughed happily.
