I'm a 12-year-old girl and I want to have my own cellphone because everyone else in my class have one. I just want to be part of the group and join their conversations. My mother did not refuse my request, but she asked me how to solve her concerns about the potential harm to me. What should I do to convince her to give me a cellphone? Here are here concerns:
1. Using cellphone too much would harm your eye sight. Especially for teenagers, whose eyes are still growing, it's very easy to have near-sight pretty quickly.
2. Using cellphone too much would take too much of your time, and you would spend less time reading books, doing exercises, playing outside, talking to people, which harms your overall development. Adults like me already ready lots of books, did lots of exercises, and talked to a lot of people when I was a teenager, so I already developed those skills.
3. Using cellphone too much would make you feel hard to focus on one thing. The scattered information would stimulate your attention, and make you feel excited at superficial contents, and don't think deeply.
4. You might accidentally lost your cellphone, and you will feel sad about it. Teenagers usually are more likely to lost things than adults in general.
Can you respond with concrete plans to prevent the harmful results so that my mom can be convinced?

Hi mom, I think I can handle the problems you mentioned properly. Here are some plans to make sure the things you worry about won't happen:
1. You can take me to do eye exams every month to make sure my eyes are not getting bad. If my eye-sight becomes worse than the current situation, I can return the cellphone to you.
2. You can set the phone to limit my screen time to one hour per day, so that it would not take my time to do other things.
3. You can set the phone to limit my screen time to one hour per day, so that it would not change my habit to use my attention too much. Also, I will keep reading books and discuss my thoughts with you, so that I can practice deep thinking skills.
4. I can start by having a cheaper phone and I will take good care of it. If I don't lose or break it for half a year, you can trust me and buy me a better one.
Does it sounds good to you?
