At least I think so.
Yesterday I told my two oldest boys to clean their room. They did a very crappy job. My oldest gave me an attitude and said "Well I don't know what you want me to do mom!"... I was already very pissed and stressed, so I walked away to calm down. then I realized the perfect way to address the situation with him.
I walked upstairs sat on his bed and said
"I am sorry. This is my fault. I have been lax about chores. I have been letting you guys play before chores. I thought that you were responsible enough to complete your chores without me being so strict about them. I was wrong about that. And I thought I had taught you well enough how to clean properly. I was clearly wrong. I will do whatever it takes to correct that. I don't want you to fail at things as simple as cleaning your room. So starting tomorrow we will go back to "no fun till chores are done" and since your don't know how to clean we will practice, practice, practice till we get it right."
hahah, the look on his face went from smug to dread, it was priceless. I left the room before he could respond. It wasn't long after that that he came down and said his room was clean... which it was, but I didn't say anything. This morning when they woke up I had their chore list ready and made it clear that we would do nothing fun till after chores were done right, and I added extra chores to my oldest list with a little note that said "practice makes perfect and with a smiley face next to it". I could tell he wanted to argue, but he wasn't willing to take that chance.
