I love Claire, but sometimes it's really hard not to laugh at the twisted logic of a four year old.
We told Claire she had to do something. She kept telling us she "couldn't." We told her we knew she could and she needed to do it right away. After a threat of undesirable consequences from us, she finally yelled, "Fine, I will. Even if I can't." Because then, even if she had to comply, she was still maintaining that she was "right." And that, THAT is what's all important, right???
