This is a true story that happened in my childhood. One day, I was trying to catch a butterfly(蝴蝶) in a garden. I tried many times to catch it but couldn't succeed.
Just then a man came and asked me, “Why are you trying to catch this butterfly?” I said innocently(天真的), “I like it.” Hearing this he held my wrist(手腕) hard. “You're hurting me.” I said with tears in my eyes. “So you feel pain,” he said with a mischievous(不怀好意的) smile and held my wrist more tightly更紧的). “Why are you doing this to me? I'm hurting,” I said and started crying. “I want you to feel the pain you are trying to impose(强加于) on the butterfly.” He said and then released(放开) my wrist. “If you caught the butterfly, you would hurt it as I did hurt you. So don't do this and let it go.” He kissed me on both cheeks, patted me on the head and went away. So I didn't catch the butterfly anymore.
Since then whenever I want to do something bad or I refuse to help a needy person, I think, “What if it happen to me?” Then I stop all my bad actions and do the right things.
