Dear Dick,
I've heard you want a bike like your classmates have but your parents don'隐弯伏t agree. Well, ask your parents their reasons for not letting you have this bike. Maybe they can't afford it right now or they think you'闹圆ll might get hurt. But if you really like they bike, convince them with your reasons. You can say that you'灶携ll be careful when riding the bike. Lastly, if your parents truly cannot afford it, you have to understand that and buy a less expensive one. All parents wants to give the best for their children but only to a certain extend. Now, you have to think it in their point of view. Think about it. Best regards for you parents.
