listen to ur parents, my parents still don't let me go on fb and i thank them, because before like last year, i had a secret fb that my parents didn't know about, and i just ruined my own life on fb AND wasted the time i had to do MUCHH more useful things that wasting time on fb and btw after i just got my mind back and deleted my fb, i found out that my parents already knew i had a fb, they just wanted me to understand myself lol and yeah i now see it's NO big deal to have fb or not
Try a filibuster. If that doesn't work, you can lock your doors and shut off the power to your house, preventing your parents from doing anything. Maybe after they lose a few billion dollars they'll listen to you.
How old are you? If you at the age requirement. Just tell your Mom or Dad that you can open one with them as the account owner exam John Doe (Mrs. Doe) your name comes first and your Mom comes Second. Best of luck to you.
