    I stood there listening to my father shout at the top of his voice. “Which one of you did this?” We all looked at the step. There was child’s handwriting in blue chalk there. Would he guess it was me! I was very nervous when he asked me, so I lied, “Not me, Dad.” My sister and brother denied（否认）it as well. To find out who had written on the step, our father gave us each a piece of paper and a pencil. He said, “I want each of you to write exactly what you see on the step.” I tried my best to write the words in a different way. I didn’t want Dad to find it was me. He collected our pieces of paper and looked at them. “Since none of you will admit（承认）to have done it, then I will punish you all.” I stood there and said nothing.

“I did it.” My sister stepped forward and said she had done it that she hadn’t. She was punished by not going out for a month.

I didn’t tell my dad it was I who did it until many years later. I always felt sorry because of it. I knew that I shouldn’t let anyone take the blame（承担责任）for me.
