Years ago, I lived in a building in a town. There was another building across from {#blank#}1{#/blank#} (I), and it was only a few metres away. There lived a woman whom I had never met. I could see her sit by the window each afternoon, drinking or reading.

    Several months later, I noticed her window was very dirty. Everything was not clear through the window. I wondered {#blank#}2{#/blank#} the woman didn't wash her window.

    One {#blank#}3{#/blank#} (sun) morning, I decided {#blank#}4{#/blank#} (clean) up my apartment, including {#blank#}5{#/blank#} (wash) my windows. Late in the afternoon when I finished cleaning, I sat down for a rest by the window. What {#blank#}6{#/blank#} surprise! The woman sitting by her window was clearly {#blank#}7{#/blank#} (see)! Her window was clean! {#blank#}8{#/blank#} (Sudden), I realized I had made a mistake. I have watched her through my dirty window all the time.

    That was quite an important lesson for me. Since then, whenever I wanted to judge someone, I asked myself {#blank#}9{#/blank#} (one), "Am I looking {#blank#}10{#/blank#} him through the dirty window of my heart?" Then I try to clean the window of my own world so that I may see the world clearly.
