On Memorial Day vacation with the kids at my country house and they are quite the riot when they're not whining. Ava (7) apparently has learned the "s-word," or at least she knows there is a word otherwise known as the "s-word" that she is not supposed to say - we're not clear whether she actually knows the word.
This got brought up in the car ride up here when we played a word game and were on the letter S, finding words that started with it. Her contribution was "the s-word, you know, the s-word."
Spencer (5) overheard all this and now anytime he hears something wrong or that he doesn't like he thinks it's "the s-word." Earlier he came in whining saying Ava was being mean to him and "had said the s-word: 'I don't want you out here.'"
