Did she really just say that?

I would like to think that our children are perfect and they would never say anything that was not kind. But we must be realistic and that reality hit hard last night. I am not sure where she heard it, could quite possibly be out of my mouth, but Harlee has learned the word dumb. She was mad at me one day and said "Dumb Mommy". I was shocked and she went straight to a time out. I explained to her that we do not say that word and that it was not nice. Well last night we went on our Sunday drive through Traverse Mountain. Harlee kept saying that she wanted to go to St George. I told her that Grandma and Grandpa were there in the condo with Tom and Yvonne. I said that since they were there, there was not enough room for us. So after thinking about it a minute she said "Dumb Grandma and Grandpa". Are you kidding me? She is too smart and such a stinker. Again she got the we do not say dumb lecture and hopefully this time it will stick.
