CB: Here's mine! Can you check it for me?
Me: Sure! The Rabbit Feth. Is that the rabbit's name?
CB: Oh, that was supposed to say feeth. I didn't know how to spell it.
Me: Feeth? What's a feeth?
CB: You know, a feeth, someone who takes your stuff.
Me: You mean a thief?
CB: No. A feeth.
Me: A theif. Thhhh ieeeef.
CB: No. Feeth. Ffffffff eeeeeeeth.
Me: CB, the word starts with th, not f. It's a thief who steals things, not a feeth.
CB: (looking skeptical) Are you sure?
CB: Can I check in the dictionary anyway? Just to make super-sure? I still think the word is feeth, like teeth.
Me: Go for it. T-h-i-e-f.
I then wrote down his title "The Rabbit Feth" and a brief explanation to the other teacher about the intended title. Needless to say, CB stays in his phonics group...and was actually surprised that thief was in the dictionary...and feth wasn't.
