Don't freight your answers with any notions of what you're "supposed" to do, and just see where your feelings point you. It can feel weird to be so formal about it, but if you're not used to doing it, then there's no shame in retraining yourself.
Carolyn HaxYou can't make someone agree with you, not even when you're 100 percent sure you're right.
Carolyn HaxThere has been, for some reason (or more likely an unfortunate accumulation of reasons) a trend over the past several decades for parents to do the work of parenting in the isolation of their own homes - and not only that, this trend has overlapped with the other trend of much deeper parent involvement in raising kids. That you also represent trend No. 3, more people raising kids solo, has only exacerbated a close-to-no-win situation.
Carolyn HaxOf course the thoughts and awareness are there, but it's all incomplete and often fanciful - kids know there's something to know, and they fill in a bunch of the blanks with their imaginations if their parents haven't had the conversations and/or established themselves as sources of information. It's rare that the kids know nothing at all, and the somethings they do know are often only partially right or flat-out wrong.
Carolyn HaxAnd if you're a parent who thinks you're okay because your kid doesn't have a phone or iPod yet, and/or you've used all the parent controls to filter out explicit material, you're not okay. The filters are tissue paper and your kid without a phone is on a school bus or in a locker room or at a public park with phone-equipped kids every day. And they're like all kids in exploring - by whatever means available to them - exactly what their parents are treating as too embarrassing or taboo to talk about.
