     "I swear, I didn't steal anything!" I shouted over the alarm. Obviously the security guard

didn't believe me because he seized the shopping bag right out of my hand.

     "Do you have a receipt for this?"he asked doubtfully, putting any new back-to-school

outfit (全套装备) onto the dusty floor near the mall entrance.

     "Of course I do," I replied, fishing my wallet out of my coat pocket. Elsie and Monica,

my two best friends, stood beside me. They were laughing their heads off!

     I almost tore my wallet apart for the receipt, but it  had disappeared." Let me look again,"

I said nervously. Then I looked again, and again, and again!

     My face was getting hotter by the minute and my heart was beating like a racehorse.

     Finally, I looked back at the guard and whispered, "It's not here." The guard picked up my

clothes and said, "You'll have to come with me, Miss."

     When he opened the office door, I saw a man sitting  behind a big metal desk. It was the

manager. Then I had an idea.

     "May I say something?" I asked. "I can prove I didn't steal this thing." Then I explained all

about the cashier (出纳员).She said that she had bought the exact same outfit as a birthday

present for her little sister. "We'll just see about that," the manager said and went off to find her.

Ten minutes later, I was free!

     It was terrible to be unfairly accused of something!Then I remembered shouting at my sister

that very morning for taking my new hair clips. Had she really taken them?I made a promise

that day never to accuse someone of something without proof, and I haven't. At least something

good came out of my terrible experience.
