When I was in high school，most of my friend had bicycles. I hoped I could also have it. One day I saw a secondhand bicycle，that was only one hundred yuan. I asked my father the money. But he said he could only give me half money. He should find the other half myself. So I went to sell newspapers after school. My father was pleased if I showed him the money a month after. He gives me the other fifty. You can imagine how much happy I was when I rode to school on my own bicycle.
