Parents are annoying me

So.. I have been acting so resposible and helping around the house so my parents would let me buy a cell phone.. But they still say no...how much does it cost a month if you get unlimted textin? Does it coset 10 dollers a month? I would pay for it with babysitting money!! How can I convice them to say yes? They let my brother who is 1 year older buy a truck.. But they don't let me buy a cell phone.

Texting is like $10 a month.
Sit down & talk w/ them & set rules, like if you get the phone, you'll do more chores, & help with dinner, or whatever.

just buy one without telling them...lol...just kidding. I would just hang in there, continue to be responsible and ask them again in a couple of weeks. I'm sure they'll say yes!

Everyday tell them you will feel safe with cell phone and if you can't do it I'll understand. Parents are more giving to their kids if they don't bagged. you can use the CPU to text your classmate or friends on their phones. Don't go behind your parents back they will be heartbroken.
