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