I consider myself fairly intelligent and quick witted. My sons are all to quick to knock me down a peg or two lest I should get too carried away in my own cleverness.
For instance, the other afternoon after a particularly trying day with #7 my 5 year old, I asked him in tones dripping with exasperation, "#7, why did you do that?"
He thought, he pursed his lips, he wrinkled his forehead, he screwed up his face and thought really hard, then his face relaxed and brightened as he answered confidently, "Because I'm a kid!"
Ummm, touche, checkmate and all that #7! You ARE one AMAZING kid!
