A lady who stayed in my building used to shout at me for playing noisily under her window. One day, she shouted at me as usual from her window and went inside. I suddenly got angry and threw a stone at her window. The stone hit the glass which broke. I heard a loud shout of pain and ran away. I later came to know that she had been badly injured by the shattered glass. I repented for what I had done. Though I did not tell her that I was the culprit, I was very good to her after that.
