     Fifteen is such an awful (糟糕的) age, I should know. I really wish I were eighteen. If you are an
adult, you can be your own boss. People like my parents and my teachers are always telling me what
to do. You know what I mean. "It's time for bed, Sandy." Or "Sandy, you've watched too much TV
for one night." "Sandy, stand up straight." "Sandy, you must improve your handwriting." Sandy this,
Sandy that. No one tells adults when they go to bed or not to watch TV. Besides, adults get to wear
what they like... Now it's going to be great to be an adult. Don't you agree?

     I'm Sandy's mother. Having a fifteen-year-old daughter isn't always easy. Right now, we've got a
problem. Our neighbor, Mrs. White, wants Sandy to look after her pet dog for one week. Sandy really
wants to do it, but I'm worried. She's too young and inexperienced. Well, I will never be able to relax
knowing she is all alone with a dog. I've tried to explain my feelings to her, but she won't listen. She
keeps telling me that the Whites live very near, so she can ask for help. She insists that Mrs. White
won't ask her to look after her pet dog if she doesn't think Sandy is old enough. She says I'm
"babying" her and I hate to see her mad at me. What should I do?
