Also, I suspect that some of what may make some of us more mainstream adults feel uncomfortable when it is expressed or apparent near the youngsters in our charge may very well not even register on those youngsters until it's time to talk about it, whatever it is.

The problem with kids is that they often don't know when they're supposed to be shocked and offended. ;-)

That's a great story to hear about though. I think honesty and openness are the best policy with child rearing. I say, having none of my own yet.
