Years ago, I lived in a house in a large city. The house next door was not far away from my house. Through the window, I could often see a woman read   in the house every afternoon.
Two   went by, I began to notice that her window was dirty .Everything was not very clear through the dirty window. I wondered  the woman didn't wash her window. It   looked terrible.
One bright morning, I decided to  my house, including washing the window inside. Late in the afternoon when I finished all the cleaning, I     down by the window with a cup of coffee for a rest. How
   it is ! I found that the woman's window was actually so clean that she could be seen clearly sitting by the window.
That was quite an   lesson for me. How often had I looked at others through my own shortcomings (缺点 ) !
Now, I am used to asking      whether I am looking through my own dirty window. Before I want to judge (判断) someone, I always think    than before and try to clean the dirty window so that I may see the world around me clearly.
