Know this: Your children are still not safe. No matter how many protections you have for them, your daughter may still get raped. How? Hormones. Deceivers. Lust. Genes. All of these factors are an unstoppable bullet through a seemingly unreachable barrier that you call "parental control". You should better teach your children to learn from your mistakes, learn from the mistakes of your parents aswell. And remember. Freedom is the most precious thing.
