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 the top of the mountain. That surprised us
most there was the beauty of scenes. After having a short 
rest there 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.
