There are certain words we do not use in our home. I also bring some of these rules into my classroom. For example, we use the word "challenging" in lieu of "hard". The word "can't" can only be used if it is followed by "yet." However, there is a "F" word that we do not use, and I feel passionately about this. I despise the word "fat." Whether someone is calling themselves or another person the "f" word, it just sends a wave of emotions through my body that I cannot fully explain.
