One evening, my dad asked me to buy some bread for dinner. It was dark and cold outside. I rode a bike to a store near my school. When I left the store, it got even darker, so I got on my bike right away. Then I found a woman in a white dress riding a motorcycle after me. She followed me for a long time. I rode very fast and started to cry for help, but no one was there. I was too scared and too tired to ride any faster. At last, I gave up. The woman stopped in front of me and said, "Why were you riding so fast, Ken? It's dangerous!" I looked at the woman. "Oh! It's you, Mom! You really scared me. Dad said you wouldn't be back for dinner tonight!"
