Bad Words

This morning when we were getting ready for school, Emily said, "Mommy, Nathan said the 'd' word!". I asked her, "which word is that?". She said, "he told me DUH". So I said, "Nathan, you know we don't say 'duh'". Then Emily said, "We also don't say the "S" word". "Right, we don't say 'stupid', either". "But especially, we don't say the "B" word". Now I'm a little alarmed, but I asked her anyway, "what is the "B" word"? "You know, butt", she whispered. So those are the "D", "S" and "B" words we don't say at our house!
