I think it's interesting how your students switch the pronouns when discussing morals to address some mysterious party. I'm going to go pseudo-psychologist on this and say that it has something to do with parents speaking in these terms when trying to teach kids lessons, e.g. "You shouldn't eat a cookie before dinner, since it'll ruin your appetite!" Although it's directed at the child, the kid is obviously going to perceive it as a rule, and therefore an objective truth. (I have absolutely no idea if that's accurate.) As an aside, I haven't forgotten about your postcard! I'm still planning on sending that your way, but there have been a number of complications with family and school recently, so I haven't had much time for hubski. I'll try to send that very soon!
