The F Word

Six year olds are sponges for knowledge. Some times (most times?) the knowledge they absorb is of a questionable nature. Exhibit A: One of my young pupils has learned the F word. In her excitement over knowing such an illicit phrase, she likes to write this word whenever she's given a chance. I can only assume that the F word that she has learned is F*ck, but it's hard to tell since all she ever writes is FNK. I don't know what bothers me more: either the fact that this kid wants to write the F word all over the place, or that she continuously fails to sound the word out correctly as I have taught her to do when she wants to write a word she doesn't know how to spell. Next time someone gets out of their seat to tell me about this little girl writing the F word, I had better see a U after the F.
