Trusting Ourselves?

Braden was whining to me the other day about bringing all his lego upstairs to play. I kind of have this rule that it needs to stay downstairs and he's usually pretty good about it, but once in a while, he likes to bring it upstairs and play in the livingroom. I did not want the visible mess, so I stuck to my guns and told him he would need to keep it downstairs because I don't like when he dumps it all out on the floor. He persisted by promising to not dump it all out. The best line was, "MOM...don't you trust me? (pause) I trust myself...."
