In-class Writing: contrast of conversational styles

During my teenager time in my family, I have limited freedom to do what I want. I always say to my parents: "I want that doll!" "I want to watch that TV show!" "I'd like to go travelling with my classmates." And their reply is like "Well, it depends on the results of your test." "No way. You need to do your homework first!" However, I will not be upset about their rejection. On the contrary, I will keep saying things like "Please let me go travelling with my friends. I promise I will finish all my homework in advance and get good grades in the exams!" "Please let me buy this and I will do whatever you want! "
The conversational styles of me and my parents are so different. I keep sending my requests and desires to them, asking for permission. And then they raise many conditions that I have to fulfill, indicating their authority and power. For a imaginary child like me, I always have so many dreams but I have to rely on my parents to achieve them. After all, I am just a obedient child. Their words and actions can determine all my happiness and sorrow.
