Years ago, I lived in a house in a large city. The house next door was only a few meters away from   . Through the window, I could often see a woman     I had never met doing some reading in the house every afternoon.
Several     went by, I began to notice that her window was dirty. Everything was not very clear through the dirty window. 1 wondered why the woman didn’t wash her window, it   looked terrible.
One bright morning, I decided to clean my house, including    the window inside.  Late in the afternoon when I finished all the cleaning, I sat down by the window with a cup of coffee for a rest. How   ! I found that the woman’s window was actually so clean that she could   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) !
Since then, I   used to asking myself 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 more clearly.
