英语作文a lesson from an arguement

Today is Sunday. After supper, father, mother and I went to the pardk. I sat on the back of father's bike. After a while, father said, "Girl, you should lose weight." Motheragreed with father. But I thought it wasn't bad for me. So I said, "No, I don't want to. I like to be myself. Do you know the famous actress named Fei Fei in Hong Kong? She is very fat but very popular with the audience." "But few fat people can become famous," father didn't agree with me. And mother continued, "You know, a lot of illnesses are caused by obesity, such as heart disease, hypertension and so on."
It seemed I had two opponents. I should try my best to defeat them. So I quibbled, "There's nothing to be worried about. Anyway, the medical technology has been developed so advanced." And then I directed the spearhead at mother, "You are also so fat. Why don't you want to lose weight'?"
