You could keep borrowing that person's phone, to organize meetings or whatever, so that s/he'll be convinced you need one.
Explain why you do. Most people don't need it, so you need to show why your needs are special.
You need to type in their phone number.
People need their independence, so people really need a phone from the age of 11 and over. Just tell them that they come in useful if you need to call someone as an emergency and that people of your age should have one.
They NEED a cell phone
You can convince someone that karaoke is good by constant exposure and lots of practice.
Oh honey, you don't need to convince anyone for sex. If they're not interested, move on and find someone who is. Consent is key, and if you have to convince or pressure someone, then you're doing it all wrong. Keep it classy, not creepy.
To convince someone you must sway them.
You need to show your parents how you act around a cell phone. Example, you can use your friends cell phone to "pretend" to call or text someone in front of your parents. Then, you can tell your friend that has the phone, to pretend to almost drop it, and tell them to say, "no biggy, it's just a phone." Then you will jump in and say, "that is not how to treat a phone. You need to treat it with care." Then, your parents will realize how responsible you are to care for a cell phone. Need more advice? Just ask me any question. To let you know that it is me, i will sign my name, "askCCKnow123". =D Please just ask me. Thanks.=D
I've been trying to convince my parents to get me one, but not really working out They have been warming up to the idea of it though because I told them that I ride my bike and walk to places alone, DON'T tell them that all your friends have one that would just let them know that if you need to contact someone your friend has a phone and you can use theirs, convince them that it would be cheaper if the drop the land line and give everyone in the house a cell phone ( and it probably is),ask to borrow their phone a lot because if you have it they won't and that would make them realize that they need their phone and the only way to do that is to get you one too. I hope this long answer can help you get that prized possession.
Come on to them.
You need to convince that person to help us.
You need to tell the truth in an interview, so you need to give your own reasons, not something someone on the internet tells you to say. Make a list of things that would convince the retailer whatever you think he or she needs to be convinced of.
