Too smart

You know your kid is too smart for his own good when. . .

you're at the dining table and you have flashcards with numbers from one to ten and on the bottom of the card the word is written, so there's a 6 and six underneath. And your 3 year old is just reading the word written out instead of the actual number. I didn't catch on to this until he got his 6 and 9 correct, which normally he mixes up. And I realize he is sounding out the s-i-x, instead of even looking at the number.
