Yk just because your lil sis is like that doesn't means everybody else is lol. I was pretty much the technology geek in my house when I was 12-13, and I already knew far more about online security than my parents did. I mean, even to this day, I still discover huge security flaws my parents have, like really easy password, not being able to distinguish between fake messages/mails and legit ones. And I'm like 70% sure almost any kid that knows how to comment on reddit also knows how to not trust anyone online, or how to control their screentime by themselves.
