My SIL bought the girls' a DIARY today. This is the conversation I had with Katie tonight.
Me: "Katie, are you writing in your diary?"
Katie: " No Mommy. I need you to unlock my Diarrhea."
Me: "Umm, Katie, I think you mean DIARY."
Katie: NO Mommy, it's called a DIARRHEA!"
The girl is adamant that it's called a Diarrhea.
