How do I convience my parents to let me get a facebook?

I would say it depends on how restricted you are by them because you could get one yourself if you had a good amount of freedom but you need to remember that things like school are more important and not having a Facebook isn't really a big loss. If they have already said no you can either respect them or you can try to whine enough but you would need to be really persistent to get it even being willing to be punished for not listening. Respect is better road to go down though.
