Oh, feeling like an idiot is a normal part of getting used to a new site.
I found it very confusing that the teen forum moves so much slower than the rest of the site. Chores were a huge issue for me too and I still feel that i sent my kids off into the world with inadequate skills, that my house was frighteningly messy when little ds was born, and that they had unrealistic expectations about what i was capable of doing in the way of housework while I was working outside the home (as a housekeeper, incidentally) with my infant along in the sling.
Whatever I didn't teach them, their roommates did. They survived. I handle things VERY differently with little ds.
Teenagers are very difficult and their problems bring up a lot of issues in parents that make our differences in priorities and values more apparent to each other. I have gotten replies to my own posts that were less than kind and advice that was unrealistic to my life situation and probably dished out plenty of the same to others when a hug smiley and an "I'm so sorry you're going through this" might have been more helpful.
