阅读理解二则

I try to be a good son, but no matter how hard I try, my parents never seem to be satisfied. They think I should eat healthier food, I should wear nicer clothes, and I should get better grades. And according to them, my hair should be shorter, my room should be neater, and my friends should be more polite when they come to my home. You know it isn＇t easy to be a teenager.
