     I will never forget the lesson about my window. Four years ago, I moved to a house in a large town.

One of my new neighbors’ house was only a few feet away from mine. There lived a woman. Through

one of my windows, I could see her reading by her window every afternoon.    

     Several months later, I found I couldn’t see the woman clearly. I thought her window was too dirty.

I said to myself, “Why doesn’t she clean her window? It looks terrible!”

     One afternoon, I decided to clean my house including(包括) the window. I felt tired after three hours

of hard work. So I sat down by the window for a rest. What a surprise! I could see the woman reading

there clearly again! By that time, I realized that my own window was too dirty, not hers! I really felt

ashamed for myself. I had been watching her through my dirty window in the past days!

     The experience is very important for me. So I try to clean the window of my heart before judging

(评判) others.
