I think the "total honesty" movement (liberalism, 70s) has had a deleterious affect on many aspects of civil society.
I doubt that. They know, they just don't care.
And I'm hardly an angel. I remember once when I was a kid going to see some presentation by a World War II veteran. This was about 1990. While he was talking about one of the more serious parts of his experiences, for which he was trying to form his words carefully, I farted quite obnoxiously.
Boy, was I pleased with myself.... I knew it was an asshat stunt, and that's why I did it.
Kids may do dumb things, but it usually isn't because they're stupid and don't know any better. This kid here is old enough to know what's what, and that's probably why he asked the question in the first place. To be an asshat.
