I am 17 years old ive been having constant arguments with my grandparents because they wont let me leave what so ever to be with friends,have a cellphone, let me get a job or even attempt to get my permit or license. I live in South Carolina. *** Is it legal if i were to only leave for a few hours?***

My grandmother calls the law and reports me everytime i want to get out of the house for a few moments. So, should i record the conversation between us saying "Im not running away but im leaving for a few hours"?
So, she doesnt try to put words into my mouth.
