Do they know you have an ask? Some parents are over protective, I didn't get a Facebook until 5th grade which is extremely early. I understand having protective parents, but they are just trying to protect you.
There is a lot of predators out there. They make fake profiles to attract younger people and make plans to kidnap them and people put to much personal information out there that helps them and then you could always have something bad happen to you but that is anywhere.
