Everyone lined up to buy their food. 2, after I finished eating, I was still a little hungry and wanted some 3. Soon I was sure my parents wouldn't buy me any candy. "I have to think of a plan," I thought.
Then an old lady 4 that she needed to buy something else, so she would have to get back in line again. I knew what I could do. So I rushed to her and volunteered myself. She agreed and gave me a $20 bill to get some chips.
When I reached the stand, I found 5 from our group was around. Then I spent the whole $20 buying the candy. I thought 6, "I have almost bought all the candy for the next century!" But then, I realized I should explain 7 the old lady why I bought no chips and where the whole bill had gone. 8, I had an idea. So I shouted, "I was robbed (被抢劫)!"
