Can’t stay in the same room with the opposite gender
This rule doesn’t seem too out-of-the-box. After all, with your teenager’s hormones going in every which direction, you can never tell what he or she will be up to behind closed doors. So, when the Duggar parents prohibit their kids from staying in the same room while unsupervised with their partners, this isn’t too big of a problem, right?

Well, what if we told you that this rule extends to family, as well? And not just cousins and uncles. We’re talking about brothers and sisters not being able to play with each other. Yeah, even when they’re innocent kids who still think that the opposite gender has cooties. You’ll see why this rule exists in a bit.
