In regards to the warnings before programs, I saw one a couple of years ago that made me giggle a little.
It was a documentary about last remaining cannibals in Papua New Guinea. It was heavily promoted and the Guide description was pretty clear so anyone watching pretty much knew what it was about and that there would be an interview with community members who participated before it was outlawed. It was a fascinating program.
However, at the beginning and at each commercial break, the viewers were dutifully warned that there was brief nudity. And this was in the form of the clothing styles preferred by the women of the community (generally topless). It just struck me as funny that someone settling in to watch a program about such a gory subject was going to get a "Hey, you're about to watch a show about people eating other people but just so you know there might be (whispers) ta-tas
On to my annoyance. I'm getting tired of people not respecting my parenting decisions and then getting mad at me when my kids do the very thing people said was just fine.
That was vague. Here's the deal. When my kids were small, they had a nasty habit of picking off the plates of others (particularly the ILs). I tried to shut that down but was told by my ILs, "Oh, that's okay!" I'd say, "No, it's really not okay, it's bad manners and I don't want them to think it's okay." I was generally regarded as being silly and they continued to let them pick off their plates.
I gave up trying to stop it since I was steamrolled every time. I figured, if they were fine with it, there wasn't much I could do without Causing a Scene. (For the record, the kids know that this is not acceptable to do to anyone else.)
Well, now my little kid is in school and was still snagging from Grandmas plate from time to time. Suddenly, Grandma isn't fine with it anymore and wondered aloud where she got such bad manners (as in, "Your mother hasn't taught you how to behave!")
I had a talk with Kid and she doesn't do it anymore but this is what happens when you override parents.
