When an expanded vocabulary is not a good thing

Like many parents, we fret over the television and its possible effects on the boys. As a result I was pleased a couple of days ago when Jamie asked me what "nullify" meant. I asked him where he'd heard it and he said on the Bakugan TV show. So I asked him how it had been used and we kind of reasoned out the meaning together. Well, there, I thought, he's picked up a good vocab word from the show, can't be all bad. A few minutes later, however, he asked, "Dad, can Connor ever be nullified?" Good feelings gone.
