Clouds were back in the deep autumn

This morning, I waked up and opened the window. To my surprise, the outside mountains were so beautiful and the view was as clear as crystal. I saw the clouds were back in this lonely valley. Though it is in the deep autumn, the weather stays warmly. There has been always sunny and blue sky, and no rains for a month. Since last night, the rain started to drop reluntantly. Now, I have to stay by my window and look through the valley, which is bringing some of my memory back. It seems I just arrived this valley before long. Somehow, two months have passed quietly. Later on, I have to face my students in the class, who have given enough troubles lately. I know I can’t never turn back the clock. Because students aren’t those used to be, with whom we have shared for many things together.
