My bicycle went wrong again. Tired with repairing it again and again, I decide to buy a new one. After school, I went to a shop locating in the center of the city with a friend called Jack. The black bicycle attracted my eyes as soon as we went into the store. It looked such cool that I could hardly wait to ride it. The shopkeeper told us that it is the latest bicycle. He wanted to charge me 800 yuan, that was too high for me. I just couldn’t afford for such an expensive one. Then I chose another one, which cost him only 200 yuan. It was not perfect, it was much better than the old one.
