Answer:
Dear younger sister,
I'm writing this letter to you because I am concered about your overconsumption of television. You spend many hours of the day staring at the screen in the living room. I don't want to offend you, this is for your sake, helath and time. I think you should limit your usage so that you can hve more time in your schedule to do other things. You have a life outside the TV and I want you to enjoy it. Spend more time with family and friednsa nd focus on your studies so you can graduate. You're very smart, you should put those smarts to more use. I want to succeed and I love ya.
