First Swear Word

Well....Scott's got to watch his potty mouth around our smart little two year old. Driving down the highway he left out an F bomb and Kali told him...."Daddy, don't say F*/-!" Hmmmm.. how does she know that is a swear word. I'm going to have to talk to her daycare provider...Is someone there correcting someone in front of her and saying that is a bad word? Hmmm....serious, though most won't believe it....we don't say that in front of her. Maybe it was just the tone of his voice when he said it that made her think it was a bad word.
